SOLAR CONTROLLER 12V 400W – BLUETOOTH -APP ONDA SMART SYSTEM

PRM400 Solar Charge Controller

New MMPT PRM400 solar controller for photovoltaic modules

The PRM400 solar regulator can automatically charge 12V lead-acid batteries (wet, gel, and AGM) and lithium batteries by controlling and limiting the energy supplied by the connected photovoltaic modules. It features an MPPT (Maximum Power Point Tracker) system that allows it to draw the maximum power output from the photovoltaic module at all times. The PRM400 is suitable for use with photovoltaic modules with 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 has been specifically developed to manage and expand the functions of the PRM400. The connection between the PRM400 and mobile devices is via Bluetooth and has a range limited to
surroundings of the vehicle.

The “ONDA SMART SYSTEM” APP allows you to:

• display the charging current of photovoltaic modules in real time
• view the charging power of photovoltaic modules in real time
• display battery voltage in real time
• display of the charging phase
• view the PRM400 manual
• update the PRM400 firmware
