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 off grid all in one solar hybrid inerter can be widely used in DC to AC areas, such as solar AC power system, vehicle system, RV power supply, security monitoring system, emergency lighting system, field power system, household power system, etc.

  • (Single phase 220V AC /A Hot Leg, NOT Support 110V !!! )
  • This PowMr off grid solar inverter all-in-one does not support parallel operation, and does not support phase separation!

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

(Important NOTE : when inverter work without batteryLCD 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!


  • 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.
  • >span class="a-list-item">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.

I am looking at the POW-VM3K-III. I am wondering if this will work without batteries and without AC input. I have enough solar power to run a pump. I only need to run the pump while there is enough sunlight out.
Administrator reply
Hello, our service will contact u soon.
United States
pow-VM3K-III - if I have only 4 18V 150W solar panels - is it still ok to run this inverter?
Or I need to buy 6 more panels to have 180Vdc for start?

Why do some of the inverters say they are only for lead acid batteries and not lithium ion?
Administrator reply
Our service will contact u soon.

im looking for a hybrid inverter
but i have 2 system running at my house
one grid tie and one off grid
im planning to combine them using a hybrid inverter
grid tie is running 6X200w 18vdc panels connected directly to grid tie inverter
off grid is running 3X270W 36vdc panels connected to Epever tracer 3210AN powering my 8s 24v 200ah lifepo4 battery with daly 150a bms
at night i turn off my grid tie system and run my battery to power my house
im planning to add battery and panels
house is consuming around 20kwh a day
so i want to generate enough to offset that
im also planning to get an EV in the future so i need enough power for a EV charging station
so with all this requirements can you recommend something to me?
