The good news is that solar charge controllers don’t need to add a hefty extra cost to your independent powering system. We have affordable controllers that utilize pulse width modulation or PWM charging technology as well as state-of-charge monitoring. If you’d like to go to a more premium model, you’ll appreciate incredible features such as software that uses efficient algorithms to fully adjust with weather conditions, effectively adjusting settings so that your array harvests maximum power throughout the day with less power loss. Indeed, the right solar charge controller can help improve solar efficiency.
At Agape Off-Grid Solar, we have AIMS Power controllers in 10- to 100-amp options as well as a DC quick-disconnect switch that brings additional safety and flexibility to new photovoltaic systems and other setups. Do you need a charge controller? The answer is probably yes, especially if you have an off-grid solar system. You probably do not need a controller if your solar battery is connected to the grid, as these units draw from the grid automatically.
PWM Solar Charge Controllers
PWM Charge controllers work for smaller systems for maintaining a charge from one or two panels.
