The 2050 European carbon neutrality target for Europe is a strong driver for energy storage systems. Sungrow offers both 1-phase and 3-phase Solutions, opening the possibility to get both, Hybrid inverter plus Battery, delivered from one manufacturer. This means one point of contact for the entire system. And that concerns installation, commissioning, service request or warranty conditions in equal measure.
The new Battery is designed in a modular way. Each battery module weighs only 33 kg and it is assembled just by placing the modules on top of each other, no wiring required. There is an installation video that guides technicians through all required steps of the installation.
Optimized for residential backup
In the 1-phase solution, the minimum battery capacity starts at 9.6 kWh which corresponds to 3 battery modules and can be scaled up to 19.2 kWh which refers to 6 modules per battery; while in the 3-phase solution, the modular battery can be scaled up to 25.6 kWh which refers to 8 modules per battery. Furthermore, the plug-and-play design ensures easy installation that can be carried out by only one installer in most countries.
The combination of hybrid inverter plus battery offers optimized residential backup, with a seamless transition of only 10ms (1-phase solution) or 20ms (3-phase solution) in case of a power outage. Since the price of electricity fluctuates, the energy storage system can be instructed to absorb electricity when it is cheap and release electricity when it is expensive in order to generate revenue for the customer. The system with hybrid inverter can also be retrofitted in a grid-connected home that already owns a PV installation, adding battery storage.
A number of safety features
The new 1-phase inverters feature the built-in PID recovery function, that allows the inverter to compensate for the power loss of the PV modules due to the PID polarization decay at night. It also comes with AFCI technology - in case of an arc fault, the inverter's switches open and interrupt the circuit, improving personal safety, protecting equipment, and preventing damage to the solar system.

Both the 1-phase and the 3-phase solution come with a new communication device, WiNet-S. The WiNet module combines Ethernet and WiFi connections in one port. The device sends fresh data to the free of charge monitoring platform iSolarCloud every 10 seconds. With this capability, the customer can check the energy flow and self-consumption in near real time, being totally in control of his renewable energy production. (mfo)
