I bought a house that came with the panels, inverter, and batteries. It turns out the system never worked; the app doesn't function, and the batteries have a manufacturing defect. After several messages, they acknowledged the battery defect, but they haven't responded in months. It is truly terrible to have to throw everything in the trash. How can a company like this even exist?

June 29th This is an update. We have been babysitting this system since inception in 2022. It has NOT been troublefree whatsoever. The 40 batteries that we paid for only 36 were functioning. Bluesun refused to replace these batteries, but wanted us to spend more. Now the other batteries are failing after 4 years. Poor support continues

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. Danie Rautenbach CEO, 2Zero50.

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. UPDATE Bluesun has confirmed that they will replace the machine, which is great news. Once the process is fully completed, I will update my review to acknowledge that, despite the difficulties and errors along the way, the company ultimately responded and honored the warranty.

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.

We buy 10kw system they said can run several appliencies in one time, ITS LIE. Cant turn on heater of 2kw! after turning vacuum cleaner Sistem is down! They refuse to change inverter or batteries

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!!
