Growatt Launched Its New AC-coupled Battery Inverter

As global TOP 2 energy storage Growatt inverter supplier, Growatt provides multiple storage solutions, including hybrid solution, battery ready solution, also AC coupled solution. Recently Growatt launched its new AC-coupled battery inverter MIN 2500-6000TLXA series, which can work alone without solar system or work with existing solar system, update the system to a storage system, what’s more, it can work with multiple grid types and also support backup function.

Default Working Mode

The default setting of MIN 2500-6000TL-XA is work with one meter, both single phase or three phase meter are supported. The meter installation will have some different when working for different grid types.

After installation, the meter detect the grid connection point import or export power, and according to the information to decide charge or discharge of the battery, no matter there is an existing solar system or not.

Note: When work in this mode, the other inverter information can not show on our monitoring system, so suggest to select System Retrofit work mode when work with an existing solar system.

System Retrofit Work Mode

When there is an existing solar system, the customer want to update to storage system with MIN 2500-6000TL-XA, also want to see whole system monitoring information, then need change the setting to System Retrofit mode, and select the right grid type, then follow the guide of the meter installation as below diagram.

Work with typical single phase grid diagram (L-N 230V)

When there is already a single phase solar system, and the house is also single phase grid, MIN 2500-6000TL-XA is the best choice. It can work together with the solar inverter in the same system with a three phase CT meter, CT1 will detect the grid connection point import or export power, and decide to charge or discharge the battery. The CT3 will detect the inverter’s production power, then the Growatt inverter production can be show on user’s Growatt ShineServer and ShinePhone account.

Work with split phase grid diagram

When the grid is split phase grid, and there is already a single phase solar system, MIN 2500-6000TL-XA can also work in the system with 2 CT meters. Meter 1 detect the grid connection point power direction, and meter2 detect the PV inverter output power. See above the system diagram.

Work with three phase grid diagram

When work in a three phase grid, then the system need 2 CT meters. One meter connects to the grid connection point, one connect to the Growatt inverter output side. The only difference is when the grid type is different, the meter installation have some difference, see above the system diagrams.

Compatible Battery

The MIN 2500-6000TL-XA is compatible with Growatt ARK XH Battery System, ARK XH battery is lithium iron phosphate (LFP) chemistry for maximum safety and longevity, 2.56kWh and 28kg per module, one person can easily do the installation. The battery system capacity range is 5.12~17.9kWh, users are flexible to choose suitable battery capacity.

Storage System With Backup

The MIN 2500-6000TL-XA can switches to backup mode automatically when power outage happens, and supply emergent power to the whole house. An SYN 50-XH is need to realize the whole house backup, maximum backup power up to 6000W. Meter and breakers are integrated in SYN 50-XH, which make the installation more easier. Since the MIN 2500-6000TL-XA is single phase inverter, so can only provide single phase backup. Meter and breakers are integrated in SYN 50-XH, which make it very easy to install.

System Monitoring

When the Growatt MIN2500-5000TL-XA inverter is monitored online, system information can be monitored on the monitoring platform, users can see the whole system production and self-consumption rate. Solar production include other Growatt inverter’s production. Also owner can check the battery information, for example the battery charge and discharge data, the battery SoC trendline.
