In the past, flooded lead-acid (FLA) batteries have been the first choice for those living off-grid. Although they have historically been the backbone of remote electrification, these batteries come with tradeoffs. Off-gassing, equalization charge, hydrometer readings are concepts that off-grid homeowners have come to grudgingly […]

Compared to lead-acid batteries, lithium iron phosphate (LiFePO4) batteries offer users practical advantages such as lighter weight and hands-off operation. These batteries also have longer lifetimes which makes for far less frequent battery replacements and service calls.
But many first-time buyers of LiFePO4 batteries […]

As Bob Dylan wrote, “The times they are a changin’…”. The change is now. Battery storage, on or off the grid today has produced a real game-changer. And my off-the-grid experience proves it.
In the beginning, I […]
Green Mountain Power (GMP), which provides electric utility services for roughly three-quarters of the people of Vermont, has reported significant savings from the growth of net-metered solar power and installations of Tesla Powerwall batteries, which it subsidized. In fact, during a heatwave in August it saved $600,000 because of the combination […]
Green Mountain Power is offering Tesla Powerwall 2.0 batteries to 100 eligible customers, free of charge. A $150,000 grant from the Vermont Low Income Trust for Electricity (VLITE) will pay for the cutting-edge technology and installation in the homes of low income customers with significant need for backup power reliability due to health and […]
This recent sonnen battery installation in New Hampshire is an ECO-12. It provides continuous 8,000 watt output along with 12kWh of standby capacity. It can be charged by the home’s 7.8 kilowatt AC solar array, the grid, or a back-up generator. Photo courtesy of Granite State Solar.
