What size solar charge controller do I need : r/solar
Charge controller ratings are deceiving. A "MPPT 100V 30A" does not mean it is a good fit for solar panels producing a little under 100V and 30A like you are describing. The voltage refers to input, but the Amps refers to OUTPUT.So your 1600W of solar, when dropped down to 12V requires a 133A solar charge controller (actually more than 150A to give proper overhead).
6 FAQs about [How big is the solar controller for home use]
How big should a solar charge controller be?
Let’s say you have a 400W solar panel system and a 12V battery bank. You would divide 400 by 12, giving you a minimum of 33.33 Amps. This means your solar charge controller should be at least 34 or 35 Amps. How Big a Solar Charge Controller Do You Need? Do you choose a 35A solar charge controller? Maybe a 40A or a 45A?
How much power can a solar controller handle?
A 20A MPPT charge controller can handle up to 20 amps of current at the system voltage. The maximum power it can handle depends on the voltage of the solar panels. For example, at 12V, it can handle up to 240 watts (12V * 20A = 240W). Can a solar controller damage the battery?
