# What Size Charge Controller for 800w Solar Panel? - PowMr

The size of the solar charge controller for the 800w solar panel is 60-100A, depending on the number of solar panels and the wiring method. If you are not sure what size solar controller to connect to the solar panel you are using, you can Ask PowMr's online customer service, which will provide you with the best quality service.

### What size charge controller is needed for 800 watts?

What is the size of the charge controller for an 800w solar panel? It can be a 60A controller, if your solar panel is 800W, using a 24V battery, then 800/24=33.33 amps, 33.33 amps is less than 60A, this is reasonable, within a safe range, a 60 amp solar charge controller Will not be damaged by excessive current.

What size charge controller is needed for 1000 watts?

This requires the voltage of your battery pack, which is calculated by dividing the total wattage of the solar panel by the voltage of the battery pack, and the result is the current you supply to the controller. For example, if you have a 24V battery pack, then 1000W÷ 24V== 41.6A. So 1000W requires a 40A charge controller.

How many watts can a 30 amp solar controller handle?

Due to the design of the 30 amp solar charge controller, it is only suitable for 12 volt systems, with a maximum input of 450 watts for the solar array. It is important to note that the solar panels should be connected in parallel to keep the voltage within 12V.

What size charge controller is needed for 400 Watt solar?

Typically 400 watts of solar requires a charge controller with a current rating of 20A and a 60 Volt input.

What size charge controller do I need for a 500 Watt solar panel?

A 500 Watt solar panel requires a 30A charge controller to handle most solar systems operating at peak capacity.

What size charge controller do I need for a 600w solar panel?

At this size and investment, PowMr recommends installing an MPPT controller, and a 50A charge controller for a 600w solar panel.

How many watts can a 20amp charge controller handle?

If your battery is 12V, it can handle 144W if you count it at max current. Calculation method: 1.2x10Ax12V=144W.
