Solar generator battery degradation does not usually look like sudden failure. The battery loses capacity gradually, cycle by cycle, until runtime per session becomes noticeably shorter than it used to be. This article explains what that process looks like numerically, why heat accelerates it far faster than cycling does, how to run a simple test … Read more
“3,000 cycles to 80 percent capacity” appears on most modern solar generator spec sheets. The number looks meaningful but tells you almost nothing without your own usage pattern attached to it. A unit used every day will hit 3,000 cycles in roughly a decade. A unit pulled out only for actual power outages may never … Read more
Every solar generator specification sheet includes a cycle count. Most buyers scan past it. That number, whether it reads 500 or 6,000, is the single most reliable indicator of how many years you will actually use this unit before the battery needs replacing. Understanding it takes about ten minutes. This page covers everything in that … Read more
Your solar generator is not lasting as long as it used to, and the battery is rarely the first place to look. There are four causes behind most cases of reduced runtime, and three of them have nothing to do with battery health. This guide covers each one in order of how often I see … Read more
