240V is normally and good like Coffee :-P Greetings from Germany :-P

the data on photovoltaic panels is a data that refers to the upper aquator circle 1000w/m², if you live further south or even on the aquator, the solar irradiation per sqm increases.

I have for my Batteries 250AWG in Germany is it over 120mm² so i have connected 2 blocks of Lifepo4 with Breaker and 1 fuse with 300Amps; both Blocks have 22Kwh Capacity at 48V so i have near 200Amps at Consumption Max.. Loading current is max 200Amps.

I can only recommend you Lifepo4 in about twice the size of your actually needed daily power so that the batteries last almost forever (10 years for sure)

You should measure the string voltage without connected to the inverter, mine also had only 2V today Disassembled remeasured and 1 Mosfet broken short circuit. Always first measure string voltage without load then with load when serious changes in voltage, the problem is usually in the inverter.

I think a Growatt 5kW 48V - MPPT 100A - SPF5000-ES - Growatt like this is for your system Good you can add an Batterysystem and add some Panels if you want.

definitely install an additional cabinet with fuses because on the one hand it is clearer and on the other hand it is easier for an electrician to implement. Proper installation never with plugs! Fixed installation in a dry preferably cool room and never forget the KWP specification is always...

I can not tell you unfortunately what an assembly with you costs I have built my own construction and was around 400 € for angles, screws and wooden beams. I have 30 cells a 325W installed and a battery with 22kwh in LifePO4.

To generate 62kkw at a sunny place for it 10kwp are enough. with something more one is certainly better served a plant with about 15kwp is sufficient to cover 62kwh. I generate in Germany with 9.75kwp about 50-60kwh per day. In the desert with proper sun the whole day, this is certainly easy...

You can make a so-called 0 injection with a hybrid inverter and battery. Thus you send nothing to the grid but have the full benefit of it. How many KWh do you need per day?

Better you Set max Charing to 57,8V or 58V MAX. LifePO4 has 3,65V Max Voltage! per Cell.

I think PVgis is better in configuration and Results but not easy to understand :-D

Go to PVgis you can calculate what a power you became with this cell :-)

It depends on your load, you have to calculate how much KW you need per day, ideally you make your plant 30% bigger than you need per day. The optimal orientation for you should be south with about 25-30 degrees elevation to recharge the necessary KW in winter. The battery you can choose at...
