This is a multi-function Pure sine wave inverter charger, combining functions of inverter, solar charger and battery charger to offer uninterruptible power support in a single package.

Support 48V lead acid, lihtium battery and without battery

(Important NOTE : when inverter work without battery, LCD will show error bP, this is ok, inverter will operate normal. Don't worry! )

Features

 

  • Configurable input voltage ranges for home appliances and personal computers via LCD control panel
  • Configurable AC/Solar Charger priority/battery charging current based on applications via LCD control panel
  • Compatible to utility mains or generator power
  • Auto restart while AC is recovering
  • Overload / Over temperature / short circuit protection
  • Smart battery charger design for optimized battery performance

Charger source priority:To configure charger source priority

If this inverter/charger is working in Line, Standby or Fault mode, charger source can be programmed as below:

Solar first:

Solar energy will charge battery as first priority. Utility will charge battery only when solar energy is not available.

Solar and Utility (default)

Solar energy and utility will charge battery at the same time.

Only Solar:

Solar energy will be the only charger source no matter utility is available or not.

If this inverter/charger is working in Battery mode, only solar energy can charge battery. Solar energy will charge battery if it's available and sufficient.

(Single phase 220V AC /A Hot Leg, NOT Support 110V !!! )

PowMr 230V off grid hybrid inerter support 48V lead acid, lihtium battery and without batter!

(Important NOTE : when inverter work without battery, LCD will show error bP, this is ok, inverter will operate normal. Don't worry! )

Start-up Voltage:150Vdc +/- 10Vdc

The Solar Panels must be connected in series, the max input current is 16A!

CAUTION!!

 

  • Shock Hazard:Installation must be performed with care due to high battery voltage in series.
  • Do not place anything between inverter terminals and the ring terminals. Otherwise, overheating may occur.
  • Before making final DC connection or closing DC breaker/disconnector, be sure that the positive (+) must be connected to positive (+) and negative (-) connected to negative (-)
  • Before connecting to AC input power source, please install a separate AC breaker between the inverter and the AC input power source. The recommended spec of AC breaker is 32A for 3KW and 50A for 5KW.
  • There are two power terminal blocks with “IN” (Input) and “OUT” (Output) markings. DO NOT mistakenly connect to the wrong connectors.
  • Never install the all-in-one solar charge inverter and lead-acid battery in the same confined space! Also do not install in a confined place where battery gas may collect.
  • Ensure that there is enough air flowing through the heat sink, and space of at least 200m to the left and right air outlets of the inverter shall be left to ensure natural convection heat dissipation.
