30 Amp PWM Solar Charge Controller
Equipment Type and Primary Applications
12V, 30A PWM solar charge controller for RVs, trailers, campers, vans, boats, and off-grid power systems. The flush-mount controller manages charging from solar panels to 12V battery banks and supports common positive-grounding installations.
Performance Specifications
- Rated solar charging current: maximum 30A.
- Normal solar array input: 15–22 VDC.
- Maximum solar array voltage with no-load output: 25 VDC.
- Lowest operating voltage at the solar or battery side: 8 VDC minimum.
- Maximum solar-to-battery voltage drop: 0.25 VDC.
- Night standby consumption: 5 mA maximum.
- Compatible batteries: flooded, AGM, GEL, calcium, and lithium.
- Operating design: intelligent multi-stage PWM and MOSFET charging.
- Ingress protection: IP22. Enclosure material: ABS plastic.
- Net weight: approximately 300g (10.6 oz).
Safety Features and Certifications
- Protection against over-voltage, short circuit, reverse polarity, overheating, and battery-connection sparks.
- Conformal-coated circuit board helps protect electronics from moisture and corrosion.
- UL 1741 certified.
Installation and Maintenance Requirements
Install vertically on a wall using the flush-mount design. Use stranded wire up to #8 AWG (0.2 in²) at the power terminals and tighten terminals to a maximum of 17 in-lb (1.92 N·m). Connect the battery and solar array according to the controller’s positive-ground configuration. The digital display and LED indicators show charging parameters, battery settings, system status, battery condition, and charging status. An optional external battery temperature sensor supports automatic temperature compensation.
