Battery storage

Your own energy when you need it.

We match battery storage to generation, consumption and the purpose of the project. It can increase the use of solar energy and, when properly designed, power selected circuits during an outage.

Why add storage?

We define the purpose first, then the capacity.

A larger battery does not always deliver a better result. Selection should be based on data and how energy is used.

Higher self-consumption

Surplus solar energy can be used later instead of being exported to the grid immediately.

Tariff optimisation

A properly configured system can shift electricity consumption over time, subject to equipment capabilities and the tariff.

Backup power

After separating circuits and selecting sufficient power, the system can keep key appliances running during a grid outage.

Inverter and battery storage with backup function — GreenExperts project
Backup power

Backup must be designed, not simply switched on.

Having a battery does not automatically mean the whole home will operate during an outage. We set priorities and design the system for actual loads.

  • We select critical circuits, such as the refrigerator, lighting, internet, controls and heating source.
  • We check appliance running and start-up power and estimate possible backup duration.
  • We select the inverter, transfer controls and required protection devices.
  • We test a grid-outage scenario during commissioning.
Selection step by step

A system based on data.

We inspect the installation and define the battery's purpose before recommending a model and capacity.

Analysis

We collect data about the PV system, consumption profile, inverter, distribution board and required backup.

Options

We compare capacity, power, integration method and the possible scope of backup power.

Installation

We install the equipment, protection devices and controls in line with the agreed design.

Testing and configuration

We configure operating modes and the app, and test system behaviour during a grid outage.

Our projects

Battery and inverter designed as one system.

All four photos show real battery-storage systems installed by GreenExperts, including Sigenergy, Fronius with BYD and SMA with BYD equipment.

Options

From self-consumption to deliberately designed backup.

We confirm each option after checking equipment and electrical-system compatibility.

Prices are indicative and do not constitute a commercial offer. The cost depends on capacity and power, the inverter, compatibility with existing PV, required protection devices, cable routes and the scope of backup power.

FAQ

Questions about battery storage.

The most important answers depend on consumption data and the existing installation.

How should storage capacity be selected?

We analyse PV generation, hourly consumption, the desired self-consumption level and the appliances that should operate during an outage.

Can the battery power the entire home during an outage?

Only if the system, inverter, battery power and electrical installation were designed for it. We often separate the most important circuits to extend runtime.

Can a battery be added to an existing PV system?

In many systems, yes. We first check the inverter, protection devices, grid arrangement and possible integration options.

How long will appliances run on the battery?

It depends on usable capacity, current consumption and appliance power. Once the circuits are identified, we can prepare an indicative backup-runtime scenario.
