PWM charge control for a voltage-matched solar array
Manage up to 20A of solar charging on a 12V battery system.
The RICH SOLAR BRAVO Waterproof 20 is a PWM solar charge controller for RVs, boats, vans, trailers and compact off-grid systems. It supports 12V battery architecture, up to 20A of solar current and a published maximum solar input of 25VDC.
At a glance
Match current, voltage and environment first
Published power guidance is use the current manual's panel-current and voltage limits. Unlike an MPPT controller, a PWM controller is not intended to step a high-voltage string down to the battery. Match the panel operating voltage, battery voltage and controller limits in the current manual.
System fit
Treat the array, battery and load output as separate circuits.
Plan around 0.66 lb, ventilation, service access and the IP65 environmental limit. Confirm panel voltage, charge current, conductor size, terminal torque, overcurrent protection, grounding arrangement and any optional temperature sensor before wiring.

Common questions
BRAVO Waterproof 20 system-design questions
Can I connect a high-voltage residential panel?
Not unless its full operating and open-circuit voltage remain inside the controller's published 25VDC limit and match the PWM system architecture. Do not choose from wattage alone.
Will it charge lithium batteries?
Published support includes flooded, AGM, GEL and LiFePO4 batteries. Confirm the exact lithium profile, low-temperature rules and BMS behavior before selecting the setting.
Is PWM or MPPT better for my project?
PWM can be a practical choice for a small, voltage-matched array. MPPT is generally more flexible when array voltage is substantially above battery voltage or maximizing harvest matters.
Does the controller include every cable and fuse?
No. Size conductors, disconnects and overcurrent protection from maximum circuit current, run length, terminal limits and local requirements.
