Why did you pick this product vs others?:Very good packaging very good quality. Everything came as stated and the price was good.

DO NOT BUY ANY PRODUCTS FROM THIS COMPANY....IT HAS BEEN A NIGHTMARE FROM THE BEGINNING...I HAD TO PAY AN ELECTRICIAN 3 DIFFERENT TO SWAP OUT BATTERIES AND INVERTERS...3 INVERTERS AND 6 BATTERIES LATER THE THING FAILED AGAIN...DONT BUY THEIR WHITE LABELED ALIBABA EQUIPMENT ITS GARBAGE!!!if it would let me choose no stars I would have!!!

Update: I added 2 stars to my rating because we got a partial refund for the 2 inverters that were defective and they wanted me to fix this review for said refund.I cannot give 4 or 5 stars because they put us through hell to get this fixed. It took 4 months for them to fix this issue. They would go days to weeks without responding, giving us the run-around as to why they couldn't refund us or fix the issue. It was always "our engineers are trying to figure it out".We lost out on thousands more dollars because of their lack of action. The refund only covered the cost of the inverters and not the half a year of time wasted and money put towards a power bill. This is all due to defective devices.We bought an inverter elsewhere and kept the remainder of the items.These inverters are defective. They do not work as advertised.I have been in contact with the seller since January. It is now going to be April. They have promised a refund on the defective items and I have happily agreed to return the items as well ...but now they keep giving me the run around and refuse to give me a straight answer.They want us to "wait for their engineers". No, they can solve their issues on their own time and their own dime. I am losing out on hundreds of dollars every month they push this off.I will update if this issue is ever solved. So far, we're out of thousands of dollars and have been royally ripped off with devices that are defective and do not work.

Purchased the entire solar kit. Solar panels, two 6500 W inverters and six batteries. We installed the system ourselves. It has been working perfectly. We now power our house and farm with the system. We upgraded with two more batteries because the solar panels were producing extra power and our home is in DE. The customer support was excellent. They got back to us when we needed assistance. Very happy with the system.

I had been looking for a backup solution for my house for a few months. For the rare occasion of power outages and bad storms. And something to supplement me daily usage of electricity. I decided to go with Expert Power because I had great success on a small 12v system I had installed in my RV earlier this year. I did have a couple issues at first with the 48v system, but tech support as prompt with helping me correct the issues

It’s works really well for me. 30kwh batteries cut off my electric bill from $700 to $96

I picked this solar kit up from expertpower in march 2024. The people there were great, they spent some time securing my load and making sure their product was safe for the trip. a very knowledgeable gentleman by the name of Sol answered many questions I had about the install and performance of the system. I am using it to power my cabin in the mountains with up to 3 people. I run a mid size fridge, a small water heater, and occasionally a large window style air conditioner, as well as a tv, couple dozen lights and other small appliances. Normally by sunrise I've used about 10-15% capacity. Unless i leave the ac on all night then it will use about %80 pretty impressive still. The components and housing are of very high build quality and after 7 months of continuous use it performs like new.Installing was pretty easy for a diy person though keep in Mind the batterys are heavy. Ive run welders, large saws, heaters and appliances simultaneously it is truly 6.5k output. The price was great and i didnt expect the phenomenal customer service from the people at expertpower. Ill be using them for future upgrades.
