► Important Safety Instructions ◄ Please save these instructions This manual contains important safety, installation, and operating instructions for the inverter. The following symbols are used throughout the manual: WARNING Indicates a potentially dangerous condition. Use extreme caution when performing this task. CAUTION Indicates a critical procedure for safe and proper operation of the inverter.
■ Battery Safety ● Do NOT let the positive (+) and negative (-) terminals of the battery touch each other. ● Use sealed Lead-Acid, Flooded, Gel, AGM, Lithium or Calcium batteries which must be deep cycle. ● Explosive battery gases may be present while charging. Be certain there is enough ventilation to release the gases. ● Be careful when working with large lead acid batteries. Wear eye protection and have fresh water available in case there is contact with the battery acid.
GEN ERAL IN FORM ATION The PowMr Pure Sine Wave Power Inverter Charger delivers superior performance for remote off-grid applications. The inverter is of pure sine wave capable of producing cleaner, smoother, and more reliable electricity for a user's electronic needs. The inverter is also able to charger the battery bank when AC power is connected to the inverter.
IN TRODU CTION ■ Basic System Architecture ■ Instruction to working mode Inversion priority mode ● In case of normal battery voltage, the inverter operates under inversion mode and load power is supplied by battery inversion; ● The system automatically switches to battery-powered mode if the battery is fully charged by solar energy or wind Energy through controller.
Electric supply priority mode ● In case the load is powered by electric supply, the electric supply has to pass input protection device, And filter before supplying power to load in order to ensure power stability, it can be also charge the battery(determined By charging mode) ● In case of outage or abnormity of electric supply ,the system automatically switches to battery-powered mode ● In case electric supply is normal ,the system automatically switches to electric supply mode to supply power to load ■ P

OPERATION ■ Battery Charging Stages ● Bulk Stage: The charger will supply constant current until the battery voltage reaches the ● boost voltage: The software will calculate the time charging began up until the battery voltage reaches 0.3V below the boost voltage. It uses this time to as TO and T0x1 0 = T1. Boost Stage: The charger will supply constant voltage and reduce the current slowly through this stage. The charger will stay in this stage until T1 has run out.
