Never connect soalr panel array to controller Without/Before connect battery.DO NOT connect any inverter/wind/Alternator or Charger into the charge controller directly ! You should connect with battery and add fuse .If there is a long distance between the PV array and controller or between the controller and battery, larger size wires should be used to reduce the voltage drop and improve performance. (Recommended wire size is only for reference.) How to program for Lithium Battery parameters ？ Via Remote Meter (Accessories needed: MT50 )Via Phone APP [ Android or IOS], (Accessories needed Adapter：EPEVER-BLE-RJ45-D or EPEVER-WiFi-2.4G-RJ45-D )Via PC Software (Accessories needed RS485 cable :CC-USB-RS485-150U ) , Software download : EPEVER official website or read in manual .
