Morningstar Sun Series Charge Controllers
The SunSaver offers legendary reliability and is available in 6, 10, and 20 amp models. All SunSavers are field selectable for sealed or flooded batteries. Every SunSaver model of the Morningstar controllers uses Pulse Width Modulation (PWM) technology to maximize charging efficiency. PWM is the most effective means to achieve constant voltage battery charging by switching the solar system controllers power devices. When in PWM regulation, the current from the solar array tapers according to the batterys condition and recharging needs. SunGuards PWM charging, compared to On-Off solar regulators, typically allows 30% more solar energy into the battery per day. Also, the average battery State-of-Charge is 90 - 95%, which is much more than 50 - 60% for On-Off regulators. For a complete system, be sure to check out the Morningstar SureSine 300 inverter.
