Usable capacity
kWh available in real operating conditions, not just the headline number.
A useful battery is more than a box beside the inverter. We check compatibility, usable capacity, backup circuits, protection and the consumption profile behind the recommendation.

When it makes sense
We start with the energy pattern you actually have, then test whether storage improves self-use, backup or both.
kWh available in real operating conditions, not just the headline number.
Fridge, heating, internet, lighting and selected sockets defined before backup is promised.
Inverter, protections, battery location and charging limits checked together.
