Solar and Lifeline
Hi y’all First thanks to all who have tried to help with this project I finally got my Renogy system up and running. 4 -100 watt panels on the roof. 30amp mppt controller, 2000w pure sine wave inve...

Wet batteries range from ooooogly quality to great quality and sealed AGM range from tolerable to excellent.
To compare a cheap AGM to a Rolls battery isn't fair. Keep it in mind.
And to suggest because a solar system cannot work with AGM because when camping solar cannot meet the 20% deep cycled minimum charge rate, is based on incomplete familiarity with how batteries work.
Camping with AGM batteries for three weeks straight then a return to storage where the batteries can recover 100% is fine.
In an off-grid home where AGM batteries are never allowed to recover to 100% is where problems arise. With the 20% recharge rule.
But with inadequate knowledge some folks extrapolate incomplete knowledge to absurd lengths. Giving solar AGM batteries a DAY OFF every 10 days to recover to 100% makes all the difference in the world for longevity. Some off-gridders don't know this or they reject the inconvenience of an ultra low demand day causes.
Incomplete recharging of wet batteries over time will cause crystallized sulfation which is unrecoverable battery depletion meaning greatly premature death.
But someone somewhere will twist even these basic words of advice into worthless garbage and worse yet worthless turns into hard and fast rote.
Perhaps the hoopla surrounding lithium batteries is true to some extent. But I refuse to believe lithium if goof-proof. It falls into the category of politics, religion gender car brands, and how to grill a steak.
