PVMARS provides a complete turnkey photovoltaic 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 energy storage system 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 energy storage 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).
PVMARS will expand on the configurations of photovoltaic panels, combiner boxes, transformers, and PCS+ energy storage cabinets to explain their parameters. This will enable you to better understand their functions.
PVMARS provides 50w-600w solar panels, which can be adjusted according to your installation location and area.
In this solution, each 550W solar panel constitutes 500kW PV array, and its parameter table is as follows:

From the table, we can determine that the size of a 550w solar panel is 2.279M x 1.134M = 2.58m2, and the average area of each 550w solar panel is about 2.6 square meters.
500kW = 500,000W / 550W = 909.09 Combined with the energy storage system calculation, we recommend 900 x 550W solar panels. Thus, the total area of 900 x 550W solar panels is approximately: 900 x 2.6 square meters = 2340 square meters.
500kW solar panels require 2340 square meters (25187.526 square feet) of installation space.
It is estimated that 90 combiner boxes will be needed. Combiner boxes facilitate solar panels’ connection to energy storage cabinets and have lightning protection functions.

This page is mainly about a 1MWh energy storage system combined with 500kW solar panel solutions for industrial and commercial (C&I) use.
PVMARS uses a 40-ft standard container high cabinet, equipped with a 1MWh capacity lithium iron phosphate battery. It also has a BMS system, PCS, fire protection system, air conditioning (HVAC) system, container and container auxiliary systems, etc.
The 1MWh energy storage system is very suitable for buildings, factories, towns, supermarkets, large homesteads, hotels, resorts, etc.
You can also power all daily or special electrical equipment: freezers, central air conditioners, testing instruments, medical machinery, lights, computers, and any equipment that requires electricity.
This system can help you achieve energy independence, getting off the diesel or utility grid and providing a free, green source of electricity for your life.
PVMARS’s 1MWh energy storage system will be assembled and tested in the production factory.
You only need to install solar panels and connect them to the electronic parts of the energy storage container to achieve off-grid living.
1) Multifunctional PCS (also known as hybrid inverters): can connect different power supplies – solar, wind turbines, diesel generators, and utility grids. Output port: Any type of power equipment.
2) Multiple working modes are available: battery priority, public utility grid power supply priority, solar power supply priority, etc.
3) Flexible expansion design: Each 1MWh energy storage system container can be connected in parallel to increase capacity.
4) Touch screen LCD: parameters can be adjusted according to actual conditions.
5) Quick conversion: If battery power is exhausted, the system switches to any power supply in 0.0001 seconds.
6) Remote monitoring: The PVMARS online platform can remotely monitor batteries, solar panels, and output and input parameters.
PVMARS’s 1MWh energy storage system (ESS) + 500kW solar energy is an off-grid microgrid solution.
Solar panels themselves cannot store a lot of electricity, so the system uses photovoltaic panels to generate electricity during the day.
It delivers power to your electrical equipment through the PCS and enables the ESS to store excess solar power.
At night, the ESS will release electricity and make the entire city shine.

500KW - 2MW
Direct manufacturer pricing, no middleman markups.
We are able to offer durable equipment at competitive price.
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.
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.
