Technical explanation
Distinguish nominal and usable capacity, charge and discharge power, losses and permitted temperature. Batteries can have electrical, thermal or fire risks; BMS and protection do not replace manufacturer instructions.

LFP batteryLithium Iron Phosphate — residential reference storage
TL;DR
An LFP battery stores electricity for later use. Select usable capacity, power and backup functions from hourly demand rather than a universal size.
Definition
LFP means lithium iron phosphate, a lithium-ion chemistry family using lithium iron phosphate as cathode material. Safety also depends on system, installation and operation.

Swiss context
Compare installed cost with avoided purchases after losses, forgone export income and fees. Check local grants separately; Pronovo does not directly fund a home battery.

FAQs — LFP battery
What battery capacity for my home?+
Request a seasonal hourly simulation with demand, available power, backup reserve and planned expansion. Annual demand alone does not determine capacity.
Is the battery eligible for Pronovo?+
Pronovo investment grants cover the PV installation under their conditions. Confirm any local storage grant with the relevant programme before purchase.
Sources & method
Check equipment values in the offered model’s datasheet and warranty terms. Confirm grant, permit and connection requirements with the responsible programme, municipality and grid operator.
