At my location, the maximum possible production is around 6.711MWh with my system.
* 15 LG350N1C with IQ7+
But, Panels are installed on the three different location with various direction/tilt.
When consider the installation, Maximum value is 6.314MWh
But, I just get 6.166MWh due to the shading of dome/tree.
My estimated production is 6.129MWh (NREL Model 6.185MWh),
One of critical issue with an AC coupling system is happening when battery has fully discharged.
There is no way to recover back.
So, I decide to install an addtional DC coupling
Two panasonic HIT340 module on the shed at my back yard.
2 pannels are connected in series, it can generate 680W. (practically, it can generate 760~780W).
I have installed cheap MPPT charger,
Actually, this model can support 190V input, and working up to 160V.
When I make 2s 96cell module, Voc is around 130-140V. and Vmppt is around 120V.
It is too hard to use a generic 150V charger.
but, this MPPT controller is perfect in my case.
This is final connection,
I have installed 200W 48V to 12V DC2DC for Mini-computer (monitoring), NAS (Data storage & Web Server)
and Wireless Router (to keep on an in-house network).
I have installed 30kWh battery power
The useable capacity is around 24~25kWh. and, It is enough to supply 24 hours full power usage.
or 2-3 days limited power usage at my house.
The most people charge thier computer or smart phone frequently, and try to keep in full charge status.
They have to understand that is the worst habit to use a lithium chemistry.
When keep the high charge status over long time, battery degradation is happening.
Will lost capacity permanently, this damage can be increased with the temperature of battery (device).
This is why no one recommend do not keep charging all the time, to reduce the average status of charge.
