Blue Sky SC30, 30A PWM charge controller
Blue Sky Energy
Sun Charger PWM Charge Controller
Blue Sky Energy’s Sun Charger 30 (SC30) panel-mount solar charge controller will charge a 12 VDC battery bank at up to 30 A from a 12 VDC (nominal) PV array, but cannot be used with 60-cell or 72-cell modules. It uses PWM charge voltage control (not MPPT) with a three-stage charge algorithm to charge flooded, gel, or AGM lead-acid batteries. All charge settings are user adjustable.
The built-in low-power LED digital display combines readability with very low power consumption, includes an automatic night-time diming feature and may be turned off completely.
Conformal-coated electronics, anodized face plate and stainless-steel fasteners resist corrosion. Built-in protection for reverse polarity, battery/PV swap, transient voltage, over-current, and over-temperature helps prevent installation errors from damaging the unit. The operating temperature range is -40 °C to+45 °C.
The SC30-LVD is similar to the SC-30 but includes a low-voltage disconnect & lighting-control feature via a 50 mA drive signal to a power relay with a 12 VDC coil (not included - see Converters and Controls for the Omron SPST 10 A relay which draws 44 mA) The dimensions of the Solar Boost Sun Charger 30 are 4 5/8"H x 6 3/8"W x 1 1/4"D and is covered by a 5-year warranty.
