February 2, 20242 yr Help Please. I'm just trying to confirm that I actually need a 3 phase inverter. New build- Cornwall. I'm getting confusing and conflicting advice. I thought I'd come to the Hive. I have 3 phase to the property. 7.2kw of solar and I'm future proofing for a battery. ASHP and car charger are spec'ed. I'm looking at a Fox ess 8kw hybrid 3 phase inverter. Is this the correct inverter? I've got an MCS company to commission it and sign off but they have adised me to aquire the components. It's a friend of a friend thing ! Thanks in advance.
February 2, 20242 yr It can be done single phase, but 3.68kW per phase is the limit for dno notification without pre-approval, so going 3 phase avoids the need for G99 process (which isn't guaranteed) If you source components yourself you'll need to handle the VAT reclaim on it yourself, and be sure you purchase an MCS certified inverter if you want to get the installation cert.
