For homeowners who already have solar panels installed and want to add energy storage, one of the key concerns is whether the new storage system can work reliably with the existing solar inverter while providing clear visibility of solar generation. To address this need, Sunpura is pleased to introduce a smart retrofit solution that combines the Sunpura plug-in home battery with the Sunpura dual-channel smart meter.
Using an AC-coupled connection method, the storage system can be added to an existing PV system without replacing the original solar inverter. At the same time, the dual-channel smart meter simultaneously monitors both grid-side data and PV system data, making solar production, household consumption, battery operation, and grid interaction clearly visible in the Sunpura Home Energy Management App. This helps homeowners better understand their energy flow, store more surplus solar power, and use their own renewable energy more efficiently.
🔌 Simple installation, stronger energy control.
The Sunpura retrofit solution is designed for homes that already have a working solar system. Instead of changing the original PV inverter or rebuilding the solar wiring, the Sunpura plug-in home battery is added on the AC side.
This means the existing PV system can continue working as before. The solar panels generate power, the existing inverter converts it into household electricity, and the Sunpura battery stores surplus energy when available.
The dual-channel smart meter is installed in the distribution box and comes with two sets of CT sensors. One set monitors the PV side, and the other set monitors the grid side. With these two measurement points, the system can understand where the energy comes from, where it goes, and when the battery should charge or discharge.
In practical terms, the homeowner can see:
- Solar production from the existing PV system
- Household electricity consumption
- Battery charging and discharging status
- Grid import and export
- Real-time energy flow in the Sunpura app
This turns an older PV system into a smarter and more transparent home energy system.
🔔More than monitoring, Take Control of Your Existing PV Inverter
After the Sunpura dual-channel smart meter is installed, the system does more than monitor energy data. It can also work with the existing PV inverter to support smarter energy control.
By measuring both PV-side production and grid-side import/export in real time, the Sunpura dual-channel smart meter enables the system to manage how solar power is used, stored, or limited. This allows homeowners to achieve self-consumption and zero feed-in with their existing PV system, without replacing the original solar inverter.
In short, the smart meter makes the old PV system visible, controllable, and ready to work together with the Sunpura plug-in home battery.
🔋 Keep the old inverter. Add intelligent storage.
Sunpura offers plug-in home battery solutions specially designed for retrofitting existing PV systems, including S2400, S6000 AC Pro, and U800AC.
The solution is designed to help homeowners make better use of the solar system they already own. Instead of investing in a completely new energy system, users can add smart battery storage, improve solar self-consumption, and manage home energy more efficiently through the Sunpura Home Energy Management App.
Sunpura plug-in home batteries are built for practical daily use:
- All-in-one design with inverter, battery pack, BMS, and EMS integrated
- Self-consumption mode available in the app
- Dynamic electricity tariff support
- Smart home integration for more flexible energy control
- Flexible capacity options for different household needs
- Retrofit-friendly AC-coupled connection without replacing the old PV inverter
With Sunpura, homeowners can upgrade their existing solar system in a smarter and more cost-effective way: keep the old PV system, add intelligent storage, and use more of their own solar power.
