The controller is designed with a common negative polarity. The negative polarity of the PV and the battery is located on the same busbar. Connect an RBVS (Remote Battery Voltage Sensor) to detect accurate battery voltage. The sampling distance is no longer than 20m. Connect an RTS (Remote Temperature Sensor) to remotely detect the battery temperature. - Page 5 Input power (Ppv)= Output power Input voltage (V ) *input current (I ) =Battery voltage (V ) *battery current (I Normally, the V is always higher than V , Due to the principle of conservation of energy, the I is always higher than I .

- Page 11 2.5 Mounting Warning: risk of explosion! Never install the controller and an open battery in the same enclosed space! Nor shall the controller be installed in an enclosed space where battery gas may accumulate. Warning: danger of high voltage! Photovoltaic arrays may produce a very high open-circuit voltage. Open the breaker or fuse before wiring, and be very careful during the wiring process.
