Great experience with Bluesun! They provided a customized solar solution for our vegetable greenhouse, solving both heating and lighting issues while significantly reducing our electricity costs. Previously, we relied on the central power system, and sudden outages put our crops at risk. Thanks to their expert team, we now have a reliable solar system in place, ensuring uninterrupted operation. No more worries about power failures, and we've seen noticeable savings on our energy bills. Looking forward to a long-term partnership with Bluesun!
Bluesun is an absolute con. They have no technology behind the system they sell as they just bundle products from other suppliers like batteries, inverters, panels, etc. All technical support come from the individual component suppliers and they just pass on the responsibilities to them. We purchased a 326kW system from them and it’s now junk. Batteries started failing after 1-year despite the 10-year written warranty that Bluesun gave. They tried every conceivable excuse to void the warranty and after failing at all attempts, they now avoid communication. This goes up to the management level as well. Do NOT buy anything from them. This is probably the WORST solar pv system in China if not the world!!
One star is not worth, but tryst pilot gives no other choice Purchased 20 5.42 kW batteries from them. Under a year and they beginning to fail.They badge a Megarevo inverter which again , Magarevo has not worked out it's issues either.Two companies that are selling products that should not be on the market.Don't buy anything from them
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 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.
Don't listen to people who Bluesun put up to give good feedback.We purchased 40 batteries from them and have proven with grid data and monitoring data that 25 percent of the energy stored can't be accounted for. Their battery storage system is defective. They have failed to provide a response other than YOU PAID A SKODA PRICE BUT WANT A BMW.AFTER spending over 50000usd in batteries.I will be taking this to courtBuyer be warned.
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.
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
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 themA pile of junk
