What really matters for a home battery

The right choice depends first of all on the inverter already in place and the type of coupling (AC or DC).
Huawei is very consistent with a complete new system with a compatible inverter.
LG can remain relevant in retrofit or already installed compatibility scenarios.

The profitability of a battery depends on the evening/night consumption profile, not just the purchase price.
Backup backup is a separate criterion: check what remains powered in the event of an outage.
Better a simple and well-managed system than a large, poorly exploited capacity.

Point of vigilance

Require a clear electrical diagram of backup mode and priority loads before validation.
