PVMARS provides a complete turnkey PV energy storage system solution. After we complete production, the system delivered to you can be used immediately after connections are made. You don’t need additional accessories to benefit from it.

The premise of providing a complete 1kW single-phase solar kit solution requires: You only need to submit load (electrical equipment) information, pictures/drawings of the installation location, output voltage range, and other data.

PVMARS’s engineering team can provide a complete solar system (off-grid or mini-grid solution).

It is recommended that you download this load table, compare it, and fill in the corresponding information: (This form is not mandatory. If there is no electrical equipment in use, please inform PVMARS of your budget and we will configure it according to your).

How much does a 1kW single phase solar kit cost?

1kW single phase solar kit prices US$1,086 – Gel battery design. (Valid for 30 days).

Note: If you need a quote for a lithium (LFP) battery design, please contact [email protected] to obtain it.

Tips: kVA ≠ kW, 1kVA = 0.75kW or 0.8kW
If you actually choose 1kW, then you need to pay attention if other suppliers quote 1kVA, because the power difference is a full 200W, which means you will not be able to use more electrical equipment.

Don’t choose them just because the price seems lower. You need to understand more about the other party through communication before making a decision.

Avoid purchasing unsuitable products, resulting in repeated purchases and increased after-sales costs.

PVMars provides a 1kW inverter of full power, not 1kVA. It is a solar kit that can truly start your entire load.

1kW 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 1kW single phase solar kit produce?

Based on the average lighting time of about 4-6 hours, a 1kW single-phase solar kit can generate 4.2kWh-6.3kWh per day, about 189kWh per month, and about 2,268kWh 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 rooms a 1kW solar kit can power?

An average household of one person can generally use 2kwh of electricity per day.

Assuming a 1kW single-phase solar kit generates 6.3kwh/day of power, that’s enough to power 3 rooms.

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.

1kW wall-mounted hybrid inverter

It has a built-in advanced AVR (Automatic Voltage Regulator) and toroidal transformer.
The toroidal transformer can also be called an isolation transformer (click on the orange font for more information).

AVR and toroidal transformers protect your electrical and electronic equipment (such as air conditioners, refrigerators, TVs, etc.) from possible damage caused by voltage surge fluctuations, overvoltage, and under-voltage conditions.

In layman’s terms, a sudden power outage in the public utility grid will somewhat affect the service life of your electrical equipment.

By using an inverter with an AVR and a toroidal transformer, even if you encounter an emergency power outage, you can effectively isolate these voltage fluctuations and extend the service life of your appliances.

Furthermore, AVRs and toroidal transformers are not limited to home/office equipment/industrial production equipment.

Even ships with internal power supply in the form of diesel generators can ensure the safety of electrical equipment through AVRs and toroidal transformers.

PVMars’ 1kW inverter combines advanced AVR and toroidal transformer to flexibly adjust the voltage boost and step-down for your various electrical equipment.

It is very suitable for families, primary schools, hotels, and precision instruments.
This powerful inverter is worth buying. You deserve better!

It is worth mentioning that this inverter from PVMARS has a built-in MPPT charge controller.

You do not need to connect an additional solar controller, so the solar panels can fully charge the battery directly through this inverter. The appearance is white, simple and fashionable, small in size and light in weight.

Simplifying the installation process of the entire 1000W solar energy storage system. For information on how to install the entire system, please continue to read below.

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.

Single phase: 110V/120V/220V/230V/240V ±5%

1000W solar battery

The gel battery of this 1kw solar kit is designed with 2pcs 12v150ah batteries with a total capacity of 3.6kWh.

If your electrical equipment requires 1kwh of electricity at night, a 1kw single-phase solar kit can continuously supply power for about 4 hours.

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