Sunsynk ECCO 8Kw On & Off grid Hybrid solar & wind Inverter £1,644 + vat
The best choice
A few friends have installed the same battery modules but have chosen different inverters. I can honestly say the sunsynk 8k has been the best of them. 1 of the others was returned due to not working as described and 2 of them have had issues with charging and shutting down. I have found the sunsynk to be easy to set up and has operated flawlessly for the past 6 weeks. Has all the functionality you could ever want and provided all the power without switching to grid. Negatives, 20watt constant draw from the grid and the cooling fans being a little loud on 3.5kw+, but in the garage so is not heard. Can't rate highly enough.
