Konfiguracja JBD BMS SP25S003 L16S-100A-B pod cylindryczne LiFePo4, zabezpieczenie przed mrozem (v2)

Przegląd ustawień BMS JBD-SP25S003-L16S-100A-B do obsługi magazynu energii w oparciu o akumulatory 16S2P LiFePo4 110Ah (2x 55Ah).
Konfiguracja własna bez komunikacji Inwerter - BMS. Inwerter kontroluje pracę akumulatorów w oparciu o napięcia. Inwerter pracuje jako UPS, nie mylić z ustawieniem 003.

Zabezpieczenie na zimę, termos na akumulator wykonany z używanej skrzyni 800x600x450.
