BluesunpvReviews of bluesunpv.com

Absolut enttäuschend! Ich habe bei Bluesunpv einen 10kW LFP-Akku gekauft und nach nur einem Monat Betrieb sind bereits 5 Zellen tiefenentladen, teilweise auf unter 1V! Das ist nicht nur inakzeptabel, sondern auch gefährlich. Trotz der versprochenen 10 Jahre Garantie gibt es keinerlei Reaktion von der Firma. Ich habe mehrmals versucht, Bluesunpv zu kontaktieren – keine Antwort, keine Hilfe, einfach nichts! Die Garantie kann man offensichtlich in der Pfeife rauchen. Finger weg von diesem Unternehmen, wenn euch eure Investition und Sicherheit wichtig sind! Absolutely disappointing! I purchased a 10kW LFP battery from Bluesunpv, and after just one month of operation, 5 cells are deeply discharged, some even below 1V! This is not only unacceptable but also dangerous. Despite the promised 10-year warranty, the company has not responded at all. I’ve tried contacting Bluesunpv several times – no answer, no help, absolutely nothing! You can forget about the warranty. Stay away from this company if you care about your investment and safety!

I have six of the batteries there 12 Kw hybrid inverter and all there other components it has never worked has never worked the batteries have no model or serial numbers the instructions were no help and there is no technical support I have tried to give it away but no takers I surrender.

We bought 14 pallets of solar panels as well as inverters and battery systems from Bluesun. The panels are ok but the inverters and battery had never-ending issues and it ended in a complete nightmare for us. The manuals contain conflicting information and are not being updated when products have changed. Firmware updates created more problems instead of fixing them. Their engineering support is unresponsive and unable to help. Their sales team has zero business ethics. On top of that it is difficult to communicate with them due to their broken English. We basically bought a pile of scrap metal & electronics which doesn't work and we can't return it. Please stay away from this company!

I put a 3Kw BlueSun panels on rental property and from day one they under performed and the contractor blamed Blusun and Bluesun blamed the contractor. 8 yrs on and changing tenants so I checked the system and only 25% output, took the panels down and 9 out of 12 panels are blistered on the back and 5 of those have burnt out section with black arcing on the back. These people put out panels that are not only bad but dangerous. It is a pity I can't put up photos.

Avoid this company at all costs. Over a year ago, we were convinced to install their solar systems, but they've been nothing but trouble since day one. Despite numerous calls and emails, the contractor who installed the systems has been utterly unhelpful, and Bluesun’s customer service is no better. They promised support and warranties in the initial contract, yet we've received no official warranty documents to back up those claims. The systems themselves—comprised of a 50 kW and later an upgraded 100 kW system along with their BMS and batteries—have been defective and malfunctioning continuously. The 50 kW system failed within the first year, and the 100 kW system started having issues just weeks after installation. We are now stuck with what appears to be 40 faulty batteries, and both the contractor and Bluesun refuse to offer any meaningful resolution. It's been one year now, and we are nearing $30,000 in additional expenses! Despite having bills to support these claims, Bluesun has not offered any reimbursement, refund, or aid, even within the warranty period. This has been an incredibly frustrating and costly experience.

Do not purchase anything from this company. They sold us two systems that never worked. They gave us warranties on the proforma invoices but HAVE REFUSED TO SEND US ANY WARRANTY DOCUMENTS.They rebadged Megarevo Inverter both 50 and 100 kW. Combined it with their BMS and batteries. The systems never worked. properly and less than one year LATERthe 50 kW is down. We had upgraded to a 100 kW system and 6 weeks later is malfunctioning. Their 40 batteries are defective and are refusing to replace them A pile of junk

they are a scam company, they sent the material but they didn't help me at all when I had problems, a solar panel broke from the lower part a week after assembly due to the temperature change, I asked for a replacement and they no longer responded, blocking me everywhere I hope that company is banned from selling in Europe

This company is a "big shame" for China, they are real cheaters // never buy from them. I bought a 15kwp + 20 kwh batterie from them but after 1 year its still not working and they stopped to respond and provide warrantie services. My client near got crazy because if them. This company is cheating clients by selling inverters and batteries which never working, build on very old technology (not state of the art), the sales and their support and engineers are totally unskilled, do not understand the basics of batteries and inverters The "so called" Managers are unabel to help, i chattend with a totally useless lady. After 1 year testing and exchanging (wrong) parts they stopped to respond. I replaced all with a serious supplier, big loss project, never again. Never buy from them, i get them to court, they have assets in a germany warehouse i will go after to compensate the damage, If anyone want to join, pls. get in contact.
