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 3kW 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).
3kW single phase solar kit prices US$1,990 – 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, so 3kVA = 2.4kW.
If you actually choose 3kW, then you need to pay attention if other suppliers quote 3kVA, because the power difference is a full 600W, 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 3kW inverter of full power, not 3kVA. It is a solar kit that can truly start your entire load.
Strong anti-cracking, heat spot protection
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.
Based on the average lighting time of about 4-6 hours, a 3kW single-phase solar kit can generate 14kWh-21kWh per day, about 626kWh per month, and about 7,517kWh per year.
Solar panels generate power related to the amount of sunshine in your local area. Click on this article to learn more.
An average household of three people can generally use 3kwh-5kwh of electricity per day.
Assuming a 3kW single-phase solar kit generates 21kwh/day of power, that’s enough to power 5 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.

Reliable thunderstorm & surge protection
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’ 3kW 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 3kW solar energy storage system. For information on how to install the entire system, please continue to read below.
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
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%
Three phase: 380Vac/400Vac±10%(customized 190Vac/200VAC)
The gel battery of this 3kw solar kit is designed with 4pcs 12v200ah batteries with a total capacity of 9.6kWh.
If your electrical equipment requires 3kwh of electricity at night, a 3kw 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.

500KW - 2MW
We have seen an immediate reduction in our energy bills and a change in our power consumption patterns since we installed the PVMARS off-grid solar power system. And PVMARS IOT is so smart to remind me why my battery is running so fast. We can also contribute power back to the grid over the summer, which is a big plus.
Our broadcast station is located at the top of the mountain, and we have used diesel generators before. We worry about the diesel transportation of the generators, maintenance, and voltage instability every day.
The current power source is the 30kw hybrid solar wind energy system. In our limited budget and installation area, PVMARS recommends using a solar wind system. This can reduce the battery footprint, but also provide a 24-hour uninterrupted and stable power supply.
It’s awesome how much I save on my partner’s bill with 10kw solar and battery package, but for me, it’s the peace of mind that I can use our electrical appliances knowing that we have clean energy. I’ve already recommended them to family members because they’ve been friendly, upfront, and responsive.
500kw solar energy storage system has operated in our remote countryside for two years. This week, Dunsborough experienced another blackout. Now we are happy to tell you that our town is not affected. All houses keep the lights on, use refrigerators, surf the Internet and listen to music to relax. This is thanks to PVMARS solar company, which customized the solar battery system according to our town’s electricity demand. This has greatly improved our local residents’ happiness index.
There was no problem with the installation, the instructions and online remote video install guidance were great, the system is working great and I’m producing 90% of my power. I just got my first bill back, last year $1290, this year $119, it’ll pay for itself in two years at this rate. You just have to adjust your times for power usage and you’ll save a lot.
The 5kw solar storage system was installed in 2018. We were initially attracted to the idea of using lithium batteries at night while solar power supply our house during the day. In addition, it can also provide seamless grid failure protection. At that time we did not know that the main city power had been cut off, until we saw outside, originally brightly lit streets and houses, because there is no electricity change to dark, to realize that the city grid has been cut off. And our house because of solar energy, to achieve power independence, electricity freedom.
