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 reminds me why my battery runs 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 diesel generator transportation, maintenance, and voltage instability every day. The current power source is the PVMARS hybrid solar and wind energy system. PVMARS recommends a solar wind system. This can reduce the battery footprint, but also provide a 24-hour uninterrupted and stable power supply.

We installed PVMARS solar storage system was installed in 2018. We were initially attracted to using lithium batteries at night while solar power supplies 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. We saw outside, originally brightly lit streets and houses because no electricity changed to dark, to realize that the city grid had been cut off. We have achieved power independence, and electricity freedom for our house thanks to solar energy.

PVMARS 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 electricity battery system according to our town's electricity demand. This has greatly improved our residents' happiness index.
