We have a quote for the following 4.725kW System, southeast suburbs, Melbourne
15 Seraphim Blade 315W panels
Sungrow 5kW inverter
Installed on flat roof, 2 storey with good access.
Price $6200 before state government rebate and loans.
After a site inspection it has been determined that it is impossible to run DC cable to switchboard area and there is no suitable location for external inverter. Micro inverters are the only option and the developer of building has already installed AC cabling from roof area to switchboard in preparation for Solar.
We have been quoted $2700 extra for upgrade to Enphase micro inverters. This seems excessive
What are your views on original quote and cost to upgrade to micro inverters?
