Enphase Energy: Home Energy Management and the new IQ8 microinverter

The all-in-one solution expands the Enphase Energy System and now integrates and controls heat pumps and EV charging stations to maximize self-consumption. Jan Lengerke, Sales Director Austria and Switzerland, explains how this works.

Getting ready to have 31 Q Cell 405-watt PV panels installed (12.5 kW) system with 31 Enphase IQ8A Inverters, mated to an Enphase IQ Controller. We will add batteries next year, leaning towards the Tesla Power Wall 3 (available this fall) or the new Enphase 5P. Can't wait to celebrate Energy Independence Day aka EID.

Unfortunately, Jan, Enphase will only provide a 15 year warranty in Australia, not 25 years like in Europe. Why??

Can you name a installer for germany, Berlin please ❤

This would be a good and safe system for my apartment with a South flat roof, I would have to have the battery in a cupboard, does it make any noise?...

​@@StephenWalker42no noise

Nice idea, but the price of the panels more than doubles having a £150 extra cost to each panel

[@Marc-ww7cc]

You remove the cost of a standalone string inverter, plus micro-inverters tend to have a much longer service life than a traditional string inverter. To compare, you need to calculate which is most appropriate for you, and you should factor in full lifecycle costs, which should include efficiency, shading, maintenance/replacement complexity, mixture of panel orientations, etc, etc. Plus potentially some other soft factors like monitoring and so forth.

@@Marc-ww7cc I agree, but if one of the micro inverters does fail, it maybe cheaper to replace the actual unit, but you would have to include the scaffold price.

[@Marc-ww7cc]

@@Piccyman1 going on available stats, enphase microinveters seem highly reliable (dramatically more so than optimisers, for example). You need to crunch the numbers. Enphase include a payment to help cover the labour cost of replacement in the case of failure (search labour reimbursement).

@@Marc-ww7cc Ok, that's good, they must be sure about the reliability of the micro inverters.
