Is a 20kW hybrid inverter worth it?

Andy of the glen writes... 20kw Hydbrid inverter (with 24kw batteries) with 15kw panels. Inverter size needs to cover the maximum instantaneous power draw of the house. Battery capacity needs to cover a reasonable portion of night/low sun days, or they are not saving anywhere enough to be worth it.

What size solar inverter do I Need?

The inverter should closely match your panel capacity (80-100% of the array size). For example, if you install a 6 kW solar PV system, you’ll need a minimum 5 kVA inverter. When you install your solar system, your solar provider should discuss inverter options with you, as well as assess your system to determine which size inverter you need.

What is the difference between kW and KVA in a solar inverter?

Solar inverters are measured in kVA (kilo-volt-amperes), which is a measure of apparent power, while kW is a measure of actual power. In a 100% efficient system, kW and kVA are the same. Solar inverters are available in various sizes. Residential solar inverter sizes typically range from 1 kW to 10 kW, depending on the home's energy needs.

Are inverters worth it?

Inverter size needs to cover the maximum instantaneous power draw of the house. Battery capacity needs to cover a reasonable portion of night/low sun days, or they are not saving anywhere enough to be worth it. Your consumption patterns, and overall household power consumption should steer this, in my view.
