Below are the product parameters and pictures of the 12kW single-phase solar kit.

12kW Single Phase Solar Kit Description

Solar panel

Strong anti-cracking, heat spot protection

Topcon solar panels packing

PVMARS provides monocrystalline and polycrystalline solar panels from 50w-600w.

Among them, monocrystalline N-type TOPCon solar panels are currently a popular option because their high conversion efficiency and low degradation rate make them more efficient than P-type solar panels.

How much electricity can a 12kW single phase solar kit produce?

Based on the average lighting time of about 4-6 hours, a 12kW single-phase solar kit can generate 46,4kWh-69,6kWh per day, about 2088kWh per month, and about 25,056kWh per year.

Solar panels generate power related to the amount of sunshine in your local area. Click on this article to learn more.

So, what’s the maximum number of houses a 12kW solar kit can power?

An average household of three people can generally use 8kwh-10kwh of electricity per day.

Assuming a 12kW single-phase solar kit generates 69,6kwh/day of power, that’s enough to power 7 houses (families of three).

Every home’s electricity usage is very different, so when choosing a solar system it’s imperative to contact a professional solar team to get a solar system and quote that’s right for you.

12kW single-phase pure sine wave inverter

PVMARS conventional inverters can choose between MOS tubes and IGBT modules, but we recommend IGBT modules.

The IGBT is more efficient than the MOS tube, but the price will also increase accordingly (if you’re interested in the MOS tube inverter, please contact us).

An IGBT (Insulated Gate Bipolar Transistor) is a super-electronic switch that withstands extremely high voltages.

The AC voltage of a typical house is 220V, and the paper-thin IGBT chip can withstand 6500V. And it can flow 200A of current!

It is very suitable for precision instruments, factories, hospitals, and large shopping malls.

This powerful IGBT inverter deserves your house. You deserve better!

How do single-phase 220v and three-phase 380v AC output voltages differ?

For most 220VAC appliances, the voltage is single-phase. Such as air conditioners, fan, light, TV, and so on.

BTW, PVMars can design double/dual voltage output, which means L1+N =110V – L2+N=110V – L1+L2=220V.

If you need, please contact [email protected] to get the price of dual output inverter

Split phase capable/dual output voltage

For most 380VAC-415VAC appliances, the voltage is three-phase. Such as motors, power pumps, central air conditioning, industrial equipment, and so on.

Please note that single-phase solar systems cannot carry three-phase loads.

12kW solar battery

The gel battery of this 12kw solar kit is designed with 20pcs 12v200ah batteries with a total capacity of 48kWh.

If your electrical equipment requires 10kwh of electricity at night, a 12kw single-phase solar kit can continuously supply power for about 5 hours.

PVMars can design battery capacity based on your actual loads and usage hours.
