Solar panels and home battery
The ZinVolt Core stores available solar power for later use. Discover how the system works and calculate which Core capacity you can have checked first.
Saving solar power for later
Solar panels often generate electricity before your home needs it. The ZinVolt Core can store available solar power and deliver it to your home later. Furthermore, the net metering scheme will end on January 1, 2027, making self-consumption more important.
From January 1, 2027, you will no longer be able to offset electricity you feed back into the grid against electricity you consume later.
Electricity you do not use immediately can go into the battery instead of straight to the grid.
This helps you get more from your own generation and depend less on expensive electricity periods.
From generation to storage
See when solar power is used directly, goes to the battery, or becomes available later. The P1 dongle PRO helps the Core recognize grid consumption and delivery.
Your home first uses the solar electricity being generated. The surplus then goes to the ZinVolt Core.
Any surplus is automatically stored for later.
This lets you use more of your own solar energy in the evening too.
In the app, you set the price limits for automatic charging and discharging.
During a power cut, connect suitable appliances directly to the Core.
One expandable Core system
The ZinVolt Core combines 4 kWh storage, an integrated inverter, and smart control. With one, two, or three ZinVolt Link modules, the same tower grows to 8, 12, or 16 kWh. The appropriate capacity mainly depends on when you feed electricity back into the grid and when you draw power later.
Modular design
A Core works independently with 4 kWh of storage. You can easily add 1, 2 or 3 ZinVolt Link modules later.
Up to 3 towers can provide a combined 48 kWh of storage. The right configuration depends on your generation, consumption and connection.
Check out the ZinVolt Core1 Link doubles storage to 8 kWh without a second inverter.
Core capacity check
This check uses only your grid import and export for a cautious initial estimate. Your panel count, household size and future plans do not automatically increase the result.
The result stays within 4, 8, 12 or 16 kWh per tower. If information is missing or unusual, we refer you for personal advice.
Initial estimate
4 kWh1 × Core
8 kWhCore + 1 Link
12 kWhCore + 2 Links
16 kWhCore + 3 LinksWe divide the lower of your annual grid import and export by 365. This is only a conservative upper limit for the average energy that could be shifted per calendar day; it does not predict daily battery use.
Accurate sizing preferably uses the median of at least 28 representative days of P1 data, spread across several seasons. A specialist also checks your meter cupboard, phase connection, peak power, installation location and future plans.
From indication to working system
The capacity check is a preliminary first indication. For the definitive proposal, we will check your energy data, connection, placement, and future plans.
Net consumption, back-feed, and preferably a P1 profile form the basis for the capacity advice.
A specialist checks the meter cupboard, phase, peak load, and a suitable location for the system.
The Core is installed, configured, and typically connected via a separate circuit and isolator switch.
After the connection, you will see generation, grid import, export to grid, and storage in the ZinVolt app.
Insight and control
Track energy flows and battery status in the ZinVolt app. Choose an appropriate mode and set charging schedules or price limits where necessary.

Frequently asked questions
The exact configuration differs per home. Always have the initial indication checked before making a final decision.
Your home first directly uses the solar power generated. Any available power that you are not using at that moment can go into the Core. Later, the Core can supply that stored energy back to your home.
One Core Tower is available with 4, 8, 12, or 16 kWh. A good choice considers grid import and export at the same times, preferably using several weeks of P1 data. Annual values only provide an initial indication.
No, not responsibly based solely on the number of panels. Power, orientation, shade, measured yield, and the time of day you use electricity collectively determine how much energy can actually be shifted.
Yes. The Core starts with 4 kWh. With a maximum of three ZinVolt Link modules, one tower expands to 8, 12, or 16 kWh.
The Core operates on one selected phase. In the case of a three-phase connection, a specialist must determine which phase and connection are suitable for your home.
No. The Core has a separate backup output for suitable devices, but it does not automatically provide emergency power for the entire home.
Yes, the Core can charge and discharge within set price limits. Without solar panels or a measured energy profile, determining the right capacity requires a personal assessment.
