PWM Solar Charge Controllers
Simple, dependable pulse-width-modulation controllers for small and high-voltage solar systems. Cost-effective 3-stage charging from the 10A CC-HLS for home lighting to the 240V CC-PWM-HV that turns any inverter into a solar inverter.
Which PWM solar charge controller do I need?
- 12V battery, up to 10A (home lighting): CC-HLS 12V 10A PWM solar charge controller
- 12V, 24V, 36V or 48V battery, 20A or 40A: PWM-PPL PWM solar charge controller
- 72V to 240V battery bank, 20A or 40A (turns an existing inverter into a solar inverter): CC-PWM-HV high-voltage PWM solar charge controller
If your solar panel voltage is much higher than your battery voltage, an MPPT solar charge controller will harvest more energy from the same panels.
When is a PWM controller the right choice?
For small 12V systems where the solar panel voltage sits close to the battery voltage, a PWM controller is a reliable and very cost-effective choice. For 12V to 48V battery banks up to 40A, see the PWM-PPL PWM solar charge controller. Systellar’s PWM range uses microprocessor-controlled 3-stage charging (Boost, Absorption, Trickle) and supports lead-acid, Li-ion and LiFePO4 batteries. The high-voltage CC-PWM-HV series even powers existing 72V–240V inverter banks directly from solar.
