Technical FAQs 4

Which IQ7 microinverter should I use?

The IQ7 can be used with 60-cell modules up to 300W/350W while the IQ7+ microinverters can work with 60 or 72-cell modules up to 400W/440W respectively. IQ7X should be used for 96-cell modules, while the IQ7A can be used for high power 60 and 72 cell modules. Enphase has no enforced DC/AC ratio.

Are 60-cell and 72-cell solar panels the same?

However, both 60-cell and 72-cell solar modules use the same cell technology, and they work out to the same price from a cost-per-watt perspective. Either option can be used in residential or commercial installs – the ideal choice depends on your array layout and space constraints where you will mount your system.

How many inverters do you need for a 12 kW solar system?

Inverter: one or two inverters of a combined 10 kW–15 kW A 12 kW solar installation in a farm near Berlin utilized a 10 kW inverter with excellent results—saving a couple of hundred dollars on initial cost and still registering peak output. 3. Equate Load Requirements, Not Panel Watts It's not solely about sunlight—actual usage matters, too.

Should I oversize my inverter?

Oversizing your inverter now might save you from having to replace it later. Upgrading from 7 to 9 kW inverter on the average American home with an electric vehicle saves a headache—and downtime down the road. 4. Panel-to-Inverter “Oversizing” (DC/AC Ratio) Oversizing panels to inverter capacity is a standard procedure, i.e., 1.2 DC/AC ratio.
