- Dual USB sockets and timer-based load settings
Product Overview
The PWM solar charge controller connects a compatible solar array, lead-acid battery and DC load through separate screw terminals. Its LCD and three-button interface provide access to system readings and load-control settings, with two USB sockets for compatible devices. Select the current configuration that matches the system design; no solar panel or battery is included.

Compatibility & Notes
Use only with a suitable lead-acid battery and a correctly sized solar array. Connect the battery before the load and panel, following terminal polarity. Mount on a firm, ventilated surface near the battery and keep the controller dry. The illustrated electrical table is specifically for 10A, 20A and 30A units; do not apply those limits to the other selectable current configurations.
