So, instead of just doing the usual and buying some Victron and Batrium equipment and calling it a day, I went shopping on Alibaba and Aliexpress to see if I could build my entire 32x280Ah and 10kW solar panels system for under 10K Euro, keeping in mind the power and charge requirements - so not under sizing. This is what I'm getting, all including shipping and tax:
Total: €8171.43
Is this all going to work perfectly? Doubt it, but we'll see. If that BMS is any good I'll upgrade it to the 200A version which is 2.5 times as expensive, so that would become €368 for both together. It seems to be the upgraded version of the one Will finally found that had low temp cut-off. This is well under my target of €10K, and I'm especially looking forward to how that charge controller is going to be doing and what that inverter can actually handle. I'll test it all in-depth and I'll post an update once I know more.
