Review Time
We have been buying from Bluesun for more than 3 years.
We have imported more than $5,000,000 in industrial and commercial hardware from Bluesun and vouch for their honorable nature.
We have visited their factories numerous times in Hefei.
Sometimes cultural differences and timezones make trading difficult, but Bluesun has never walked away from a ligitimate warranty claim.
We continue to buy commercial and industrial systems from them.

I am very dissatisfied with both the product quality and Bluesun’s after-sales service. A defect occurred in one block of the PV battery storage system during the stated warranty period. The supplier initially responded and acknowledged the issue. When discussions moved to replacement of the defective battery block and shipment arrangements, the supplier ceased communication. More than 10 contact attempts were made through Emails and other available channels, with no further response received. As of this review, no replacement or resolution has been provided, and the warranty issue remains unresolved.I am extremely dissatisfied with this PV product and with Bluesun’s after-sales support.The product quality is not reliable, and the lack of communication from the seller makes the situation worse. A battery storage system is a critical and complete silence from the supplier during the warranty period is unacceptable.Based on my experience, I cannot recommend this product or this supplier. Buyers should be aware of the potential risk if warranty support is needed.
Very bad experience with both HV batteries purchased. SOC level jumping, droping on daily basis, errors when battery is fulll, display freezing, very low quality ... Solar power plant stops due to battery errors.Long term deception by Bluesun about resolving errors inefficiency in resolving them and now they are also become unresponsive.They no longer answer any communications, phone calls, emails.I strongly advice against any purchase from Bluesun company.
Bluesun inverters are extremely poor in quality. Just two months after installation, my system developed critical failures.Although the company has responded, they only sent me a replacement board that did not fix the problem. Up to this day, I still haven’t received a definitive or concrete solution.This has been a brand-new system for my home, and instead of enjoying the investment, I’ve been dealing with constant errors, downtime, extra costs, and stress for months.I’m sharing this so others can make informed decisions before investing in this brand.
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.
