PowMr 4200W Solar Inverter 24VDC to 220V/230VAC, Pure Sine Wave All in One Hybrid Inverter with Built-in 120A MPPT Controller, for Home RV Off-Grid System, for 24V Lead Acid and Lithium Battery

I bought the 3000 watt model for my shop and liked it so much that I bought this split phase 240v one for the bus so I can run a welder. It has worked perfectly so far. Uses about 1.8 amps at 52 volts on standby but I generally leave it off unless I’m using AC power or the sun is shining. It charges off the shore power at 40 amps/52 volts. There are no loads that I have here that make it even work hard. Welding at 160 amps is nothing. The well designed menu lets you control every conceivable aspect of the operation of the machine. I wouldn’t mind seeing some slightly nicer cable connections where the various wires enter, they all work and are big enough for properly sized electrodes though.

I got it for my parents' house. It works flawlessly. And it is up to the specs. It was easy to install. The only thing is that the WIFI module does not work. The culprit is the inverter. It does not provide power to the WIFI module. I tried connecting a network cable too and it does not show in the router. It is disconnected. I would love to get support but it is very difficult and the PowMr website provides no support to issues like this. The inverter, beside this, is wonderful.

I wanted to charge my sister's Tesla from my solar system so I got this 240vac all in one inverter. The unit arrived promptly and well packed however the chassis still suffered multiple damages - front & back & bottom. After hooking it up, the unit powered on and supplied 230VAC but the display didnt lit up (see pictures) and I wasn't able to change any settings. I contacted seller because I want to get it to work instead of taking it down. (It's very difficult to install it due to the tight space design). The rep replied back promptly and offered me $100 off or send me a replacement LCD. Also, she authorized me to open it up and try to fix it without voiding the warranty. I opened it up and found the LCD ribbon cable was completely detached due to the poor quality clue was used. It simply cracked and break away from the connector. I plugged it back and close it up then the LCD was back on. That was easy fix. I moved on to adjust the settings and found out the menu options were different than the manual I downloaded from their website. Long story short. I asked for additional discount and they kept saying $100 was the best they can do. Back and forth we spent weeks and didn't landed anything constructive so I returned it before 30 days.

El aparato en si sebe todo bien y de buena calidad todavía no lo instalo cuando lo instale comentare nuevamente

I didn’t read the info to well and this was wrong voltages for me so I returned it, it did look nice and well made

Better than I expected thinking of buying another one

Muy recomendada me encantó este producto y muy util

I waited several months to give this review so that I could use it in a system before reviewing it. As far as performance goes I have no complaints. Is connected to 6 400W solar panels in series, with 4 100AH 12V Batteries in series. We have 2 Small Refrigerators, 58" TV soundbar, Midea 12,000BTU AC (runs 24/7) We cook with a small microwave, Instant Pot, electric griddle, Ninja coffee machine, and a rice maker. We always have enough power. No overloads. What I don't like and modified, (voids the warranty, I'm sure.) The connectors for all of the inputs and outputs are cheap and flimsy. It is very difficult to get them secure without stripping out the screw heads. I can't speak to idle consumption, because our system is never Idle.

Ho aspettato un po’ prima di scrivere la recensione. L’inverter per il momento funziona in maniera eccellente. Nel manuale non c’è scritto ma ha il neutro flottante e quindi ha bisogno di un relé di messa a terra ed un differenziale curva F sull’uscita principale verso i carichi. Per il wifi ha bisogno della sua chiavetta dedicata. Non facile da reperire ma una volta trovata è plug&play e quindi non c’è da fare niente. Quando va al massimo della produzione fv si accendono le ventole per il raffreddamento che un po’ di rumore lo fanno, ma tenendo l’inverter in un locale separato, non si sentono. Ha bisogno di almeno una batteria per poter funzionare correttamente. Tutti gli attacchi ed i morsetti sono ben indicati. Ha 41 voci nel menù da dover settare per ottenere un ottimo risultato senza farlo sforzare quindi c’è da leggere il libretto.
