This is where things got complicated. At the time, we had closed the deal with JA Solar and a Goodwe 5048-ES, but the Goodwe had to be 14A DC because if you look at the specifications of the panels in this power house, they all operate at around 13A DC and most inverters on the market are limited to 11-12.5A DC. A lot of people here will tell you that this is precious and that the panels will rarely operate at their power limit, but let's be honest, do you think it makes sense to buy material that is “limited” from the outset? Not in my mind. And this is where we lost some more time. Solar FV contacted me to say that the supplier had mistakenly sent them a quote for the Goodwe ES 11A (the standard) and not the 14A and that they couldn't get the 14A, but that they would try to find a solution. Fine. Note that I had already paid the deposit for the contract. And now's the part where you think “eish, you've run out of money, it went really badly, etc”, but no. As soon as I'd paid the deposit, Solar FV ordered the panels directly for delivery to my house, which in themselves cost more than the deposit (I thought this was an incredible act of trust!) It did the same with the structure. And then it was a question of finding an inverter. We still had time to exchange the panels for the S20 series, which operates at 11A, but I wanted the S30 series (it's 11BB, more heat-resistant, newer manufacturing technology, higher efficiency, less thermal loss, etc., and no, it's not just because it's more powerful, guys!) and again, Solar FV respected the request. We looked at various alternatives, but the real difficulty was finding a hybrid inverter that could handle at least 14A DC. SMA inverters above 3kw can handle 16A... but they're not hybrid. Three-phase inverters typically do... but we needed a single-phase inverter. So we started looking at alternatives such as Deye (but it didn't inspire much confidence...), Turbo Energy (strangely similar to Deye), some Growatt that support 13.5A (not ideal but possible) and finally, after some research in the Australian market (which as you know is a benchmark in solar) I arrived at Sungrow. Now, Sungrow is a very interesting Asian brand (which is said to have bought much of SMA's know-how), but which has a very significant track record of success, performance and lack of problems. Several reviews I saw from Australia (because there isn't much information about sungrows) put growatt and solax on one level, goodwe and huawei on a higher level and put the sungrow on a completely different level from the previous ones, on a par with Fronius, which for them is - THE - reference. One of the companies claimed to have installed more than 800 Sungrows without a single problem in recent years. I found it so interesting that I went to check it out. And yes, they have some very interesting features that I invite you to get to know. Above all, it solved my problem because it accepts 16A DC x2 MPPTs. For those who are curious, a 9.6kwh Sungrow battery is the price of a 5kwh Huawei battery and the Sungrow will provide more than 6kwh AC from the battery, whether it's the 3, 4 or 5kw version (because yes, my dear, Huawei has hybrid inverters for 1000 euros, but then don't forget to look at the price of the batteries, the backup box, the UPS switching times, the charging/discharging powers, the DC limits, the efficiency.... ... in short, I have my own opinion of Huawei, but it's relevant in this context). Analysis done, I think I've ended up with a fantastic solution, which includes recent panels with very good performance, a very interesting inverter, the ability to put in HV batteries at the price of Pylontech LV and with a monitoring system that includes a meter and a platform with lots of information. I have Solar FV to thank for supporting me in researching and acquiring material that is new/unknown to many people and for not giving up or trying to force something else halfway through. Perhaps this is the difference in having two electrical engineers, with a degree and a master's degree, running the company.
