ABC Depth of discharge (DoD) How much of a battery's nameplate capacity may be used. Lithium iron phosphate packs commonly allow 90 95 %. Glossary ABC Usable capacity What you can actually take out of the pack, after depth of discharge, the reserve and the end of warranty ageing allowance. Glossary ABC C-rate Continuous discharge power as a fraction of capacity. A 10 kWh pack at 0.5C delivers 5 kW. A short, heavy backup need is limited by C rate,... Glossary ABC Hybrid inverter A single unit that manages PV input, battery charge and discharge, the grid connection and a backup output for the essential circuits. Glossary
