Storage with a purpose. Backup with a plan.

kWh and kW answer different questions

For illustration, a 10 kWh battery with a 20% reserve leaves 8 kWh before conversion losses for routine use. This is an arithmetic example, not a recommended size or a promised runtime.

What size is worth exploring?

Compare your evening and overnight use, solar surplus, tariffs, reserve preference and future appliances. Ask for a realistic comparison of at least two suitable capacities. Check how often each could charge and discharge across the seasons.

Will the lights stay on?

Backup needs compatible equipment and a deliberate circuit design. Confirm the supported circuits, phase arrangement, power limits and whether solar can recharge the battery while the grid is down. These features vary between systems.

A fridge, lights and internet present different requirements from cooking, heating or a water pump. Tell us which loads matter most; we will assess their actual requirements.

VPPs, tariffs and control

A virtual power plant can involve an operator controlling battery charging and discharge under a contract. Compare payments, electricity rates, reserve control, exit terms and warranty conditions. Do not assume the best plan is the one with the highest headline credit.

Our main solar-and-storage choices

We lead with Sigenergy SigenStor, followed by GoodWe ESA. Compare the matched inverter, usable storage, backup arrangement and operating controls for your property.

Already have solar?

Bring the inverter model and monitoring history. We can discuss a compatible storage addition versus changes to the existing setup. Confirm any gateway, inverter, wiring or monitoring work in the scope.
