⭐ 1/5 | FR User: Firstly, the item took over two months to arrive, and I had already received other AliExpress orders placed much later. Secondly, the item arrived defective; I ordered two solar controllers, and after installation, one of them released the sacred blue smoke. I managed to repair it, but the question arises: why did I pay money to wait so long for delivery and then have to repair it myself? Lastly, the packaging looked like it had been through all seven circles of hell. So, draw your conclusions.
⭐ 5/5 | BR User: The box was very dented, but apparently, the product is okay. It takes a little while to power on.
⭐ 5/5 | BR User: My second charge controller and performing as expected for a 48V battery.
⭐ 1/5 | BR User: The equipment arrived and did not work for my 48V system. The seller advertised it as 12V, 24V, 36V, and 48V automatic, but the equipment came as 12V and 24V only.
⭐ 1/5 | UA User: These are scammers! They sell the cheapest controllers, designed only for lead-acid batteries, as Easun 6048. The photo shows what I received after ordering an Easun 6048. The manual states it’s a MiniSolar 60A-V124. It has nothing in common with Easun 6048, neither software nor hardware!
⭐ 1/5 | ES User: It doesn’t work, you can’t return it, it’s not MPPT. AliExpress is terrible, doesn’t accept returns. Easun is a very bad brand… Choose Victron, it has nothing to do with this.
⭐ 1/5 | BR User: Did not send the product I bought. I bought a 60A and received a 20A. No comments.
⭐ 1/5 | BR User: I bought the 40A and received the 20A. How do I exchange it and receive the 40A I purchased?
⭐ 1/5 | IT User: The controller does not match the description, not reliable.
⭐ 3/5 | UA User: Menu setup is confusing, but otherwise it’s normal.
⭐ 2/5 | TH User: Not easy to set up. Not for LiFePO4 batteries.
