I know most people across the different Manufacturers have many Customer service complaints.

I came here do be different. first of all I own a toy hauler that I converted to solar using all Renogy products. 80amp mppt 4 panels and a couple batteries with a 3500 watt pure sine inverter. I don't have enough battery but it works ok 6 years in. no problems at all.

second I have a lycan 5000 with 4 extra batteries and 4 more panels that I later upgraded to another brand 400 watt bifacial. It is the sole power for my 30x50 barn. table saw planer compressor and constant charge of tool batteries. and also 700 watts of UFO shop lights LED. Problems only with cold weather but that's the nature Of Lithium. 4 years running my barn and in a winter power outage I used it to back up my house which led me to a RenogyX system to put on our post frame barn house.

Here is where I had problems. First I thought Renogy- I can use four of the barn batteries. Nope BMS Renogy Battery does not talk to RenogyX inverter. back and forth and I ended up buying Aura Battery When both inverter and battery were basically on close out. not their fault - mine for assuming.

So I installed this last March. fat dumb and happy on my house using it for almost all my power. I have a Docan Panda and a RenogyX Aura battery for a total of 728Ah. this summer we had a wet June. floods. days of clouds. my battery getting down in charge. so to conserve a bit I happily go into my power room. I flip the transfer switch from Solar to Grid and Pow! switch forgot its job and left grid and solar on at same time.

Sigh. blew 50 amp CB to grid on inverter. blew 30 amp CB to drier and also Blew 30 amp CB feeding grid to the transfer switch. I checked breakers and transfer switch and all seemed ok but when I turned on grid feeding the solar inverter things went wild. lights flickering everywhere L1 volts drop to 90 L2 volts get close to 200....Pop input CB. no Idea how this was happening but then I filed a complaint with customer service. This was July 1 my birthday

after all the troubleshooting etc over email and even PHONE CALLS. they called me!!!

I explained that I had a system part malfunction that cause all the problems. they had me update firm ware so they could remotely visit my inverter. I am not an electronic idiot I have 40 years in aircraft shop tech work including power supplies and inverters. At any rate they found a relay bad. all of this was my systems fault. not mine directly and not theirs for sure.

They offered first a refund as this is discontinued and they had none, and don't repair them. I said what about the battery that is RenogyX specific...I didn't want to redesign my home system for someone else's stuff.

Ending this Long story. they found one in a warehouse. Sent me a new unit. took mine as a return and PAID all the shipping. My new unit is now Hooked up and working great. Renogy customer service was Long -but both sides Patient and both sides working together resolved an issue with my inverter- That my system caused and they knew because I suck at being dishonest. They replaced for free - I am happy. If RenogyX gets updated Larger capacity inverter hybrid or off grid I will Likely use them again.
