Float charging, sometimes referred to as “trickle” charging occurs after Absorption Charging when the battery has about 98% state of charge. . The answer is simple yet critical: Float mode is a maintenance phase where your solar charger reduces voltage to prevent overcharging. But there's far more to it—this feature is the unsung hero of battery longevity. The float-on charge controller keeps the batteries at a safe level. . What is FLOAT CHARGING on Controller? I have been using PWM controllers 60A for my 8 12V Solar Panels for 3 years now. My Controller stopped working suddenly. It is a little heavier and the cover is metal. When the battery voltage reaches the specified absorption V - bulk stops - and absorption starts.
