PowMr 6200W Solar Inverter 48V DC to 220-230VAC,Off-Grid Hybrid Inverter with 120A MPPT Solar Charge Controller, Work with 48V Lead Acid & Lithium Battery

I have 2 product of Powmr where i love them, i bought this model "POW-HVM6.2M-48V-N" for the 220/240v becuase i do have 3 airconditions 220v. I did test the 3 aircondition and the inverter works great better then expected, BUT i notice that the inverter was using Battery power and not solar power to feed the 3 equipments, i was looking why and notice in the manual that after 1 KW the inverter will go to Discharge Mode and will not charge the battery even we have 2.8 kw of solar power. and 3 aircondition was at 3.kw. so basically it is just a power inverter from 48v to 220v. If you keep your power load under the 1 kw it will charge the battery and basiclly 1 aircondition can be running durring the day.one nice thing for me if the POW-HVM6.2M-48V-N is turnoff and you have PV comming in it will charge the battery even there is not turn on.See pictureshope this info can help you.*UPDATE:-------------------I change my 3 star to 5 star...After doing some changes in the setting i did find out, that putting the Battery to LIP despite the manual ses that is/need a communication with the battery and that is why i dint change it.after setting the battery type to LIP and the battery charging did start while there was a power load from my home.Note:Make sure you have enough Solar power to feed the wattage to your equipment, otherwise it will take it from the battery (see Update picture).Good Inverter 220V

Easy to set up, but...When I flipped the switch on the circuit breaker suggested in 'frequently bought together', the inverter turned on even though the on/off switch was off. after a second or two it turned itself off. I switched the circuit breaker off and tried again. The circuit breaker (supposedly good for 600v) sparked and issued white smoke. My PV array puts out about 420v. POWMr supposedly can handle 450v. I turned on the inverter running on battery power. Switching the PV array after that on and off had no visible effect. It still seemed to work as an inverter/charger but setting the configurable settings with the up/down/enter/esc buttons did not work as documented. Sometimes pressing the buttons did nothing. Sometimes the up button would move the selection down. I haven't contacted the company yet, but I am not sure I want to pay the shipping to have it fixed. It's a shame. The advertised features sounded pretty good.

It works, but when solar panels are feeding energy the output of this inverter fluctuates it is not stable. Therefore if you are going to use for air-conditioning which have very sensitive electronics it won't work when there is sunlight. The quality is not premium.

I initially ordered the 3600W 230V, a week later its price dropped with > $130 from beginning while the 6,2K is just $50 higher compared to the 3,6K before sale. So, I returned and go for 6,2K with more capacity, I thought the 3,6K is enough but after reconsidering the total load and decide to move to off-grid completely.Currently I just have 2400W with 4 panels (each 600W) but will expand later to 4800W for filling the two windows left of the house. I use the flexible panel high efficiency and paste behind the glass of the window that direct sun light for at least 4-5 hours a day, I got about 8-10 KW a day in average.For storage I have four 12V -50A sealed lead-acid battery in series connect, they seem not enough when the sun light go off, the battery just last for 5 hours then the inverter pulling power from grid to supply the house.I will plan to get 1 more battery bank later when they are sale off, battery is most cost in the system, and need a financial plan to get it.I recommend this 6,2KW inverter since they are now on sale, to the 4-5 persons house, you need at least 5K-8K inverter, need more headroom for potential load that you not sure for its coming in future, once you installed it, you will not change the whole thing after just 1-2 years, right?Update sept 18 2023, after buying the Huawei Smart Li 48V 100AH lithium battery and replace with 6 355W Longi black frame solar panels, the system produces average 8-9Kw hours in 6-7 hours a day, the peak watt I can get in some highest sunny day is 10KW a day which use for load and charge the battery at the same time, the battery discharges for 10-12 hours at 450w more or less, so I just consume from the grid about more than 1 KW from the grid only for the gap time after discharge, the bill now just 40-60Kw a month.the good thing that saves me for thousands of dollars is the UPS battery replacement for the UPS, with the solar hybrid system, I just keep the UPS as backup source for the servers running 24/7 without cost me hundred bucks for buying UPS battery packs to replace every two years or less since the solar system now becomes the big capacity UPS at lowest price.In short, the solar + this hybrid inverter + battery can be a good choice for those who operating the small private cloud system like mine that run seamlessly while the same configuration and resource from Amazon AWS can cost me thousands of dollars monthly.PowMr is not the best choice, but they are good start for p/p base on the price.I'm happy with this solution now.

If your not going to really use this then it will be ok if using 60% capacity it will overload it

Excelente servicio

I bought the first unit sort of confused by reveiws, it only has two output wires, so I suppose it is meant for european markets where everything uses 220 volts, in america we expect something that generates 220 to have a neautral wire so we can use each leg of the 220 with the neautral for 110 as well, that said people that are trying to run 220 appliances this will work, 220 does not require a neautral or a ground to work, ground is earth, literally the earth. I am completely off grid with 5 air conditioners 6 fridges and a 1000 watt pool pump, no backup power needed. we weld off of this inverter while air conditioners are also running. We have a separate 110 inverter but any other 6000 w 220 inverter is twice the price. For long life making a dry space is important. The first one killed it for 5 apartments and a restaurant for 4 years 247 but we had a failure I think related to just too much exposure to super wet air, not water but on rainy days it was super moist in that area.
