Blue Sky Energy Blue Sky SC30 PWM Charge Controller 30 Amp 12 Volts

Unlike the other Blue Sky Energy solar charge controllers, the Sun Charge 30 does NOT use maximum power point tracking (MPPT) technology. It is strictly a PWM type controller. This means it is not quite as efficient as their other models, but it is significantly less expensive. Blue Sky Energy's new Sun Charger 30 solar charge controller charges 12 volt batteries at up to 30 amps. The Sun Charger 30 uses precise PWM charge voltage control combined with a sophisticated 3-stage charge algorithm to optimally charge flooded, GEL or AGM lead-acid chemistry batteries. To periodically condition flooded lead-acid batteries the Sun Charger 30 will also perform a manual or automatic Equalization charge. The built in low power LED digital display combines excellent readability with very low power consumption, includes an automatic night time diming feature and may be turned off completely if desired. The high accuracy display shows battery voltage, solar charge current, and computes total solar charge amp-hours produ...
