When choosing a power backup solution you are looking for an option to power your lifestyle. A backup that can allow you to watch tv, work from home, make coffee, and still have some juice for your phone. Solar generators are a great option as they are renewable and environmentally friendly. The option to recharge using solar panels makes it even better as the sun is a free resource that you can access from anywhere.
A 1000-watt solar generator will run a TV, a small heater, blender, and even a full-size refrigerator. It can even power a single-pot coffee maker and a low-wattage electric grill. There are different ways you can make a 1000-watt system. These include portable and non-portable systems. You can choose to buy a fully built 1000-watt system or build one from scratch.
1000-watt Portable Solar Generator
A portable solar generator is a great option for those who want to go off the grid while it cannot power an entire house, This generator can be used to power a variety of appliances, and it’s perfect for those who want to be prepared for an emergency.
The Jackery 1000 built is rated at 1000 Watts and 10002 Wh. As earlier mentioned this can power a small heater, blender, and some higher wattage devices such as single coffee makers and some electric grills.
The Jackery 1000 comes with three different types of ports: AC, DC, and USB. It has three AC ports used to plug in standard appliances. The DC port is used to power 12V DC appliances. The USB port is where you charge devices such as phones and tablets.
The Jackery supports pass-through charging which means it can be used while it’s charging. This is a great option as it can offer some form of uninterrupted power supply system especially when you use a solar panel to recharge. Jackery recommends using the 200-watt SolarSaga Foldable and recharging the power station in 7 hours.
You can charge a solar generator in three ways; from an AC outlet, a carport, or from a Solar panel. The AC outlet usually takes the shortest time and the carport will take the longest. Charging from the AC outlet will take around 5 hours and 14 hours from the carport.
However, as much as the power station is portable it is heavy. At around 13 pounds this is some weight to carry around. The manufacturer also claims a 2000-watt surge watt rating however the power station shuts down when anything rated above 1000-watt pulls from it. This is true for most solar generators as this function is limited as some appliances may cause an over-discharge.
Can you Combine Two Portable Solar Generators?
The simple answer is yes, you can connect two portable generators together. However, the inverter rating will not change. You will combine the watt-hours of the two batteries for more runtime but this won’t increase the inverter rating if you looking to power high wattage devices. Some solar generators like the Jackery allow you to daisy chain them to combine running time.
To make a 1000-watt hour system you can combine two 500-watt power stations or add a 700-watt power station to a 300-watt power station. A power station rated at 700 watts can run a fair good number of appliances while the 300 watts can charge your portable devices and run some appliances for a short while.
What is the difference between Watt Rating and Watt-Hour Rating
A Solar generator combines a battery, inverter, charge controllers, inputs, and outlets to create a power station that you can charge and hook up your appliances to use.
While these components have combined to make a new application, their size and ratings still determine what devices you can run.
Inverter Rating (Watt-Rating)
An inverter is a device used to convert direct current (DC) to alternating current (AC). An inverter’s wattage rating is the most important specification in the solar generator. This is where we get the 1000-watt rating from.
The wattage rating determines how many appliances an inverter can power at one time. It is also important to consider the surge wattage of an inverter. The surge wattage is the amount of wattage that an inverter can provide for a brief period of time. This rating is important for appliances such as air conditioners and refrigerators, which require a large amount of wattage to start up.
If you have an appliance that has a running wattage lower than 1000-watt but the surge watt is higher than this rating then it will not run.
Battery Capacity (Watt-Hours)
Capacity in batteries is measured in Watt-Hours. A watt-hour, or watt-hour, is a unit of electrical energy equal to one watt dissipated for one hour. The watt-hour is also the energy equivalent of the power consumption of one watt for one hour. To run a 30-watt TV for 5 hours you’ll need 150-watt-hours of energy.
Solar Generators will usually match the inverter rating and the battery capacity. So a 1000-watt solar generator will have a 1000-watt hour battery to at least run the 1000-watt in an hour.
However, the Watt-Hour rating is derived from the battery and the voltage;
Watt-Hour = Voltage x Ah
A 1000-watt solar generator will have a voltage of around 20v so the battery size will be around 50 ah. The amp hour rating is a measurement of the current output over time example , a 1 amp-hour battery should be able to continuously supply 1 amp for an hour.
For example, if you have a 50 Ah battery you can draw out 100 amps in an hour but that is not advisable, you can also draw 10 amps over 10 hours or 20 amps over 5 hours.
These functions are embedded into the solar generator through the BMS that prevents overvoltage, under-voltage, undercharging, and overcharging. More on this later.
Combining the Watt-Hour Rating of your devices and matching it to your solar generator can give you an idea of how long you can run your devices.
| Application | Wattage | No of Hours | Watt-Hours |
| TV | 30 Watt | 3 hours | 90 Wh |
| Gaming System | 40 | 2 hours | 80 Wh |
| Coffee Maker (Single Serve Pod) | 800 Watts | 12 Minutes | 160 Wh |
| Mini Fan | 30 Watts | 4 hours | 120 Wh |
| Car Fridge | 60 Watts | 6 hours | 360 Wh |
How to Calculate Working Times for a Device
If you like to calculate the working times for a device you can use the following formula:
Working Time = Solar Generator Watt-hours x 0.85/ operating power of the device
You’ll multiply the Watt-hours of the device by 0.85 because of system losses. This is due to the wiring, DC-AC conversion, and efficiency.
For example to get the working time for a 30-watt mini fan
= 1000 x 0.85/30
= 28 hours
What Solar Panel to Charge a 1000-watt Solar Generator
You can charge a solar generator in three ways; from an AC outlet, a carport, or from a Solar panel. The AC outlet usually takes the shortest time and the carport will take the longest. Charging from the AC outlet will take around 5 hours and 14 hours from the carport.
Using a solar panel can give you an endless source of solar power. You can use a 200-watt solar panel to fully charge the 1000-watt Solar panel in around 8 hours. With good sunlight conditions, you can do it in 6.5 hours.
How to make a 1000-watt Solar System
A 1000-watt solar generator is a lifesaver as it can run your most essential appliances. But it’s also heavy and bulky and therefore not really that portable. If the main reason you are looking for a 1000-watt system is the capability and not portability you can still look into building the system yourself.
We already have an idea of what a 1000-watt solar generator has in terms of its components. Well, a 1000-wat solar system will have the same in terms of the components plus the wiring.
This is what you’ll need:
Lithium-ion Battery
A lithium-ion battery is a type of rechargeable battery that uses lithium-ion cells. These batteries have a high energy density and are lighter than other types of batteries, which makes them popular for portable electronics and even solar generators.
Lead-acid batteries have been the go-to choice for renewable energy for more than a hundred years. However, with the advent of lithium-ion batteries, lead-acid batteries are becoming less common. Lithium-ion batteries offer several advantages over lead-acid batteries.
Lithium-ion batteries are lighter than lead-acid batteries, making them easier to transport. They also have a longer life span, meaning they need to be replaced less often. In addition, lithium-ion batteries can be discharged more deeply than lead-acid batteries without damaging the battery. This makes them a better choice for vehicles that frequently use start-stop technology.
Inverter
As earlier mentioned an inverter is a device that takes DC input and converts it into AC output. The inverter will convert the DC power from the battery to AC power that can be used by your appliances.
The rating of the inverter will still determine what devices you can run. You can choose a 1000-watt inverter that also has a higher wattage for surge watts (1200-1500) to ensure you can still start big devices.
Also, the best type of inverter is a pure sine wave inverter. This inverter creates an output much like the one from a wall outlet and is crucial for some devices.
Solar Panel
A solar panel is a device that converts sunlight into electricity. Solar panels are made of semiconductor materials, such as silicon, which convert the sun’s energy into electrical current.
In a non-portable system, the solar panel can be fixed to charge your batteries during the day while using and still have enough juice in your battery for using during the night. You can use a 200-watt solar panel to fully charge the 1000-watt Solar panel in around 8 hours. With good sunlight conditions, you can do it in 6.5 hours.
Charge Controller
A charge controller is a circuit that regulates the voltage and current coming from a PV panel to a battery bank. There are two main types of charge controllers: PWM and MPPT.
PWM (pulse width modulation) controllers are the simplest and least expensive type of charge controller. They work by reducing the amount of current flowing from the solar panel to the battery. This reduction in current results in a reduced amount of power being produced by the solar panel.
MPPT (Maximum Power Point Tracking) controllers are more expensive than PWM controllers, but they are much more efficient at charging batteries. MPPT controllers work by tracking the maximum power point of the solar panel. They do this by adjusting the voltage and current being sent to the battery.
Charge controllers will also have an LCD display that ensures you can check on the system. This info includes how much power is being produced, how much power is being used, and any errors that may be occurring. MPPT Charge controllers like the Victron have a Bluetooth App that ensures you can check on the system from as far as your couch.
Wiring
Wiring can be really scary for some with all these components involved. But the basics of wiring a solar system is simply connecting the positive and negative terminals of the battery to the corresponding terminals of the solar panel.
When wiring a solar battery, you will need to connect the positive and negative terminals of the battery to the corresponding terminals of the solar panel. This is done through the charge controller which will have the labeling for where you should place the wire.
When sizing a solar system, a wire gauge is an important consideration. The wire gauge determines the amount of current a wire can safely carry. Too little current and the solar system will not work properly; too much current and the wire will overheat and may catch fire.
The National Electric Code (NEC) provides tables that specify the appropriate wire gauge for various currents and distances. The NEC also specifies that the voltage drop across a solar array should not exceed 3 volts. This means that the voltage at the inverter should be within 3 volts of the voltage at the solar panels.
A rule of thumb for sizing a solar system is to use 12-gauge wire for distances up to 100 feet and 14-gauge
Other Protective Components
While the charge controller should be enough to provide cover for a small system. The bigger a system gets the more complicated it gets, and since you are powering your home and sensitive appliances it is crucial that you close loopholes that might cause any issues. The following components are not a must but are necessary for a 1000-watt system and beyond:
Battery Management System
A battery management system or BMS protects the battery from overcharging, undercharging, and discharging too quickly. Most lithium batteries will come with an inbuilt BMS but if you are assembling lithium battery cells yourself ensure to have one in your system. You also need to ensure that all the terminals of the battery are connected to the BMS.
Battery Monitor
A battery monitor is a device that displays information on the battery including voltage, current, and temperature. It will alert you if the battery is fully charged, the draw from the loads on the battery, and if the batteries are heating up.
Modern battery monitors can even relay information over Bluetooth and the internet allowing you to monitor your battery’s performance remotely.
Temperature Sensor
A temperature sensor is attached to the battery to monitor the battery’s temperature. Lead Acid batteries usually heat up when power is being pumped in and a temperature sensor allows the controller to take note of this and adjust the current going to the batteries to avoid overheating. Overheating can damage the batteries and lead to gas hazards from lead-acid batteries.
Lithium batteries can also not be discharged in low temperatures and you’ll need to disconnect them in case temperatures fall below 5 degrees.
Battery Shunt
A battery shunt is a device that creates a low-resistance path for an electric current. This is useful when you have too many wires in a circuit and have a preferred path for the current, especially through a battery monitor. A battery shunt should be connected on the negative side of the circuit. Most battery monitors come with an inbuilt battery shunt.
Fusing
You should ensure that you install a fuse between the solar panels and the charge and controller and the battery and the charge controller. This is in case there are spikes in the system your battery is protected.
Low Voltage cut-out
When using a battery in a solar system and you are drawing out of the battery even if there is input from solar panels if the draw is big enough the loads might deplete the battery. A low voltage cut-out or disconnect will disconnect the battery from the loads (or some of the loads) before the battery is completely discharged
In conclusion, solar power is a great way to power your home or even your camping trips. A solar power system for your home can provide you with a consistent source of renewable energy. A Solar Generator is a great backup option for those who want to be prepared for any emergency. It’s portable, lightweight, and easy to use, and it can be charged by solar power or a standard AC outlet. The Solar Generator is a great value for the price, and it’s a must-have for anyone who wants to be prepared for any emergency and does not want the hassle of setting up a solar system.
