Introducing the best off-grid battery on the market. It’s the perfect balance of storage capacity, cold weather, off-grid, safe, cost, and simplicity. The onboard software keep the battery for being over or under charged, it’s save Lithium Iron Phosphate chemistry and UL9540A listed with fire suppression built-in, and it’s got integrated heaters to keep the battery charging during those below 0ºC days. It’s compatible with many inverters in closed loop mode, meaning the battery tells the inverter how much to charger. no futzing with bulk, absorb, float voltages, or equalizing. They take up much less room and can be installed inside or outside since there’s no off-gassing. The outdoor model is IP65 water resistant.
Back in 2020, I custom-designed a high-quality Lithium Iron Phosphate battery ideal for Savary Island off-grid use. I knew the benefits of lithium-ion and I also knew our lead acid battery days were coming to an end. These batteries are in use at 3 cabins on Savary now. I learned a lot about lithium-ion and the positives and negatives, especially with cold weather, off-grid use. The next version of our battery needed heaters and UL listed for fire safety.
During my 100’s of hours of research, I came across EG4‘s batteries and it checked all the boxes. I ordered one and couldn’t believe the price. I tested it out and actually was everything they said it was. I then learned that EG4 is the 5th largest supplier of home backup batteries in the US, just behind the Tesla Powerwall, which doesn’t work off-grid. This was no fly-by-night company.
Now that my testing is complete, and contacted EG4 and asked to distribute them in Canada. I told them about Savary and the other islands in desolation sound and they immediately got excited. So, I shared my data with Mark Long and Dillon Worthen at Lund Electric, and convinced him to carry them. Since then, we have since installed 30+ units on Savary and many more are on the backlog.
My company called Sol49 Energy, and I’d love to tell you more about our technology.
