Calculating Solar Panel, Inverter, Battery Charger
Hello Olamide, A 40 watt panel will only produce 3.33 amps from 12 V, which is way too less for the battery in terms of voltage and current both, so your solar panel will not be able to charge the mentioned battery. Even with a boost charger the current will drop to 2 amps which is not sufficient for the battery.
For this calculation, the important distinction between PWM and MPPT charge controllers is that PWM charge controllers cannot reduce the level of current coming from the solar array. So we need to calculate the PWM''s max charging current based on the solar array''s max output current. 1. Find your solar panel''s short circuit …
