MPPT Solar Charge Controller Sizing When picking out an MPPT controller, look at the battery''s voltage, solar panel voltage, and power output. Match the MPPT controller''s voltage with the battery bank''s, like 12V, 24V, or 48V. The controller''s maximum input
This is a simple equation. Watts ÷ Volts = Amps. You take the total watts of the solar array divided by the voltage of the battery bank. That will give you the output current of the charge controller. For example, a 1000W solar array ÷ 24V battery bank = 41.6A. The rating of the charge controller should be at least 40A.
Solar Panels Current. The size of the solar controller is often in the name of how much current the solar controller handles (that is, the maximum charging current). In the market, generally, a solar controller will have 10A, 20A or 30A sizes. Some high power controllers can also handle 50A, 60A current. Even greater, 80A Solar Controller and

BougeRV 20A MPPT Solar Charge Controller: Ideal for larger systems, this controller provides high efficiency and compatibility with a wide range of battery types.
A 100W solar panel typically needs a 10A charge controller with a 30V minimum solar input to work with 12V batteries. A 150W (3x 50W) solar panel array can use a 20A charge controller for 12V batteries (10A for 24V batteries). Connecting the panels in series works for both 12V and 24V batteries as long as the MPPT is capable of
A solar charge controller manages the power going in and out of the batteries in a solar power system. It does this by regulating voltage and current. It stops your batteries getting overcharged by controlling the flow of energy from your solar panels. It also stops the reverse flow of power, which can drain and damage the battery bank, from
