This AC coupled battery storage system from SoFar solar offers tremendous value – combining the SoFar ME 3000SP with four 2.4kWh Pylontech lithium batteries to give a total battery bank of 9.6kWh. As this is an AC coupled kit it is suitable for any existing or new PV array, even those with dual tracker inverters, microinverters or power optimisers.
Monitoring is built in as standard and can be viewed via their android app. Charging from the grid is also possible meaning that customers on Economy 7 or similar can take advantage of this and store electricity overnight for use in the morning, before the PV has fired up.
As a rough rule of thumb this would be suitable for larger domestic systems over 5kW, depending on the home usage profile.
