MPPT charging for a measured 12V or 24V system
Manage up to 40A of solar charging with automatic 12V/24V detection.
The RICH SOLAR 40A MPPT Controller (RS-MPPT40) is built for RV, boat, cabin and off-grid battery systems. Its published limits pair 40A battery-charging current with 100V maximum solar input voltage and a 50A maximum PV short-circuit current.
At a glance
The four electrical limits to match first
Use the current controller manual for the allowed array wattage at the selected battery voltage. String voltage, parallel current, conductor size and protection must remain inside every published limit.
System fit
Match the array, battery and wiring as one circuit.
Allow for the 9.37 × 6.81 × 2.85 in enclosure, 4.41 lb weight, ventilation, conductor bend radius and service access. Confirm cold-weather array voltage, current, terminal capacity, grounding and environmental protection.

Common questions
RS-MPPT40 system-design questions
How much solar can I connect?
Use the current manual's array-wattage limit for the selected battery voltage, while also keeping the complete array below 100VDC and within PV current limits.
Will it charge lithium batteries?
A lithium selection is listed. Confirm the exact battery maker's required charge voltage, temperature rules and BMS behavior before choosing the profile.
Can it be installed outdoors?
Do not assume weatherproof installation. Follow the manual's environmental requirements and protect the controller and terminals from water, debris and conductive contamination.
Does the 20A load output mean 40A of appliance power?
No. The battery-charging path is rated 40A and the separate load output is rated 20A. Size each circuit and its protection for its own limit.
