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.

What is a solar panel array?

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. Battery size is measured in watt-hours (Wh) or kilowatt-hours (kWh).

What components do I need for an off-grid Solar System?

Below is a combination of multiple calculators that consider these variables and allow you to size the essential components for your off-grid solar system: The solar array. The battery bank. The solar charge controller. The power inverter. Simply follow the steps and instructions provided below.

How do I choose a solar system?

Quick Compatibility Tip: When selecting your components, make sure they're all compatible with each other, especially in terms of voltage. Solar systems typically operate at 12V, 24V, or 48V. Ensure your panels, batteries, and inverter all work together at the same voltage.
