Each battery size is 900x675x200 mm with weight at 128.5 kg or 283 lbs. Total cost with shipping $8140.
The battery is listed at 8500 cycles with 15 year warranty. 8500 cycle @ 1 cycle/day / 365 = 23 years. The warranty itself reads that the warranty life cycle power during warranty period is 64.80MWh@80%, which equals 14.34 KWh x 80% = 11.5 KWh/day x 365 = 4.1 MWh@80% / 365 = 15 years (assuming 1 cycle / day).
2021 production = 25.17 MWh and consumption = 42.02 MWh.
2022 production = 25.51 MWh and consumption = 33.33 MWh.
Average day production = 25.51 MWh / 365 = 70 KWh/day
Average day consumption = 33.33 MWh / 365 = 91 KWh/day
91 KWh/day / 24 = 3.8 KWh Reading consumption from grid 3.46 KW/h at midnight.
My intention is to only use the batteries and hybrid inverters as an UPS when we lose power. Panama don't have the peak hour rates, if we did I would use the batteries during peak hours. I was paying Panama highest residential consumer rate per KWh because of high consumption, With my inverters, I am now paying the lowest consumer rate per KWh. I have 19 KW solar panels and need to add at least another 6 KW Solar Power.
