The charge controller in your solar installation sits between the energy source (solar panels) and storage (batteries). Charge controllers prevent your batteries from being overcharged by limiting the amount and rate of charge to your batteries.

Proper Connection Steps: Follow a systematic connection process: disconnect power, connect the charge controller to the battery, attach solar panels to the charge controller, and finally link the inverter to the battery.

Yes, an 18V solar output can effectively charge a 12V battery. This higher voltage is necessary to overcome the battery's internal resistance and allow.

A quick rule is to divide watts by 10 for 12V systems or 20 for 24V systems. For more accuracy, divide the load by the actual battery voltage and adjust for inverter efficiency (typically 85%).
