Technical FAQs 4

What voltage does a solar system work at?

Solar systems typically operate at 12V, 24V, or 48V. Ensure your panels, batteries, and inverter all work together at the same voltage. When in doubt about compatibility, don't hesitate to call us! We're here to help you build a system that works seamlessly. Try different combinations of appliances in the calculator.

How many kWh does a 150W refrigerator use?

Example: Our 150W refrigerator running for 8 hours uses 1.2 kWh. Solar Panel Array: This is all your solar panels combined. Its size is measured in watts (W) or kilowatts (kW) and determines how much energy you can generate under peak sunlight. Battery: This stores the energy your panels generate for use when the sun isn't shining.

How much power does an inverter need?

The output your inverter should have depends on your needs. Most homes and businesses use 120V single-phase power. Larger appliances like stoves, washers, and dryers use a 240 V split phase. You should also keep in mind that most off-grid inverters can’t connect to grid power.

How many watts is a 12V power system?

A good rule of thumb is that if your energy needs are less than 1,000 watts, go for a 12V system. If you use between 1,000 and 3,000 watts, then a 24V system is best. If you require more than 3,000 watts, then you might even need a 48V system.
