Reminder:
1. In the mains bypass mode, the device cannot be connected to two-phase 220V AC power, that is, L1-L2 cannot be connected to L-N. 2. In all in one inverter mode, after the device is connected to two-phase 220V, please do not select the mains priority as the output priority, so as to avoid potential safety hazards for the device. 3. Do not connect the AC output end of the device to an autotransformer, so as not to affect the normal service life of the device.
Charger source priority: To configure charger source priority
If this 48V inverter charger is working in Line, Standby, or Fault mode, the charger source can be programmed as below:
Solar first:
Solar energy will charge the battery as first priority. The utility will charge the battery only when solar energy is not available.
Solar and Utility (default)
Solar energy and utility will charge batteries 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 the battery. Solar energy will charge the battery if it's available and sufficient.

PowMr 230V off-grid hybrid inverter support 48V lead-acid, lithium battery and without batter！
(Important NOTE:when inverter work without a battery, LCD will show error bP, this is ok, the inverter will operate normally. Don't worry! )
Start-up Voltage:150Vdc +/- 10Vdc
The Solar panels must be connected in series, the max input current is 18A!
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 the final DC connection or closing DC breaker/disconnector, be sure that the positive (+) must be connected to positive (+) and negative (-) connected to the negative (-)
Before connecting to the 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.

Hallo.
I have bought a 5KW Solar Inverters All-In-One MPPT Charger Controller POW-VM5K-III. It seems to work but I have a problem with the lcd display because after it turns off for the night (I still don't have batteries) in the morning the lcd display doesn't turn on anymore even if the inverter works. I have to disconnect the display pin and connect it again and it works but it's not normal. Can you please help me solve the problem? Thanks
