SOLAR PANEL REGULATOR PRM350 20A MPPT

New MMPT PRM400 solar regulator for photovoltaic modules

The PRM400 solar regulator can automatically charge lead-acid batteries (wet, gel, and AGM) and 12V lithium batteries, controlling and limiting the energy supplied by the connected photovoltaic modules. It features a MPPT (Maximum Power Point Tracker) system that allows it to draw the maximum power available from the photovoltaic module at all times. The PRM400 is suitable for operation with photovoltaic modules from 32 to 72 cells, up to a maximum power of 400W. For optimal device performance, we recommend connecting photovoltaic modules with more than 36 cells in series, regardless of the installation type.

APP - ONDA SMART SYSTEM

The "ONDA SMART SYSTEM" mobile app was developed specifically to manage and expand the functions of the PRM400. The connection between the PRM400 and mobile devices is via Bluetooth and has a limited range of action
around the vehicle.
