Product Information
8A PWM Solar Charge Controller for Boats, Gates and Battery Maintainers
A PWM controller is the simple, economical choice when panel voltage is close to battery voltage — a 12V panel on a 12V battery, for instance. It costs less than MPPT and has less to go wrong, which is why it still suits small RV, boat and shed systems.
Size the array to the limits in the specifications table.
Rated IP65. Mount it close to the battery on a vertical surface with airflow around the heatsink, and wire battery first, then panels.

Frequently Asked Questions
How many panels can I connect?
Check the maximum PV input power and voltage in the specifications, and keep the array within both.
MPPT or PWM — which do I need?
MPPT harvests more, especially when panel voltage is well above battery voltage or in cold and low light, and it is the better choice for larger or 24V arrays. PWM costs less and suits small systems where panel and battery voltage are closely matched. This unit is PWM.
Which batteries does it charge?
Check the battery types listed in the specifications and set the matching profile before first charge.
