14.34kWh LFP Wall Mount Battery

EG4 14.34kWh LFP Wall Mount Battery is LFP (lithium-iron-phosphate) — the chemistry now standard in residential storage. LFP runs cooler, doesn't have the runaway-fire risk profile of NMC, and tolerates 100% depth-of-discharge without warranty hits. It's slightly heavier and slightly less energy-dense than NMC, but for stationary residential use those are non-issues. LFP is the right choice — it's what we'd recommend either way.

EG4 14.34kWh LFP Wall Mount Battery is rated 14.34kWh nominal but 11.47kWh usable — that's a 80% depth-of-discharge limit set by the BMS to preserve cycle life. Plan to 11.47kWh, not 14.34kWh, when sizing for actual backup hours.

EG4 14.34kWh LFP Wall Mount Battery is rated 8,000 cycles to 80% DoD — that's 22 years if the battery cycles once per day, every day. In real residential use the battery typically only fully cycles 200–300 times per year (it's partially-charged most of the time), so the practical lifespan tends to be longer than the cycle math suggests. Calendar aging — what happens to the cells regardless of cycling — is the bigger long-term factor.

Yes — EG4 14.34kWh LFP Wall Mount Battery is stackable. We don't have the maximum stack capacity confirmed. Confirm with the manufacturer or installer how many units can parallel into a single bank, and check that your inverter supports the resulting battery voltage and capacity.
