1.4 Schematic Diagram for Connections Warning:Confirm the AC load power compatible with the power of the inverter/charger, AC load selected exceeding the maximum output power of inverter/charger is prohibited.
The wiring and installation methods must follow all national and local electrical code requirements. Recommended wire and circuit breaker of PV Breaker Model PV wire size 2P — 63A FBIC3000VA/24V 10mm /8AWG 2P — 32A FBIC3000VA/48V /10AWG NOTE: When the PV modules connect in series, the open circuit voltage of the PV array must not exceed max.

Step 3: Wiring Determination of installation location: The inverter/charger shall be installed in a place with su cient air flow through the dissipation pad of the controller and a minimum clearance of 150 mm from the upper and lower edges of the controller to ensure natural thermal convection.
Step 6: Connect Accessory Connect the remote temperature sensor cable (model: RTS300R47K3.81A) Connect one end of the remote temperature sensor cable to the interface⑦ and place the other end close to the battery. NOTE: The temperature sensor short-circuited or damaged, the inverter/charger will be charging or discharging at the default temperature 25 C.

3.5 Other Function 1) ) Output voltage & frequency switch When Switch 1 is in "ON" , the output voltage is selected as 230VAC, and on the contrary as 220VAC; When Switch 2 is in "ON" , the output frequency is selected as 60Hz, and on the contrary as 50Hz; NOTE: If the output frequency or voltage of the inverter/charger is to be reset, it is required to turn o the inverter/charger and power on the unit after setting.
4. Protection Instruction Protection PV Limit Current When the charging current of the PV array exceeds its rated current, it will be charged at the rated current. NOTE: When the PV modules are in series, ensure that the open circuit voltage of the PV array does not exceed the "maximum PV open circuit voltage".
5.3 Troubleshooting Fault Troubleshooting Battery Over Voltage Check if battery voltage too high, and disconnect solar modules. When the battery voltage resume to or above LVR point (low voltage Battery Over Discharge reconnect voltage), or change the battery by other ways The inverter/charger will automatically turn the system o .
