Hi all,

Long-time lurker, building my first system.

I'm wondering how big the difference really is between Lithium and AGM, because I can get some industrial AGM telecom batteries - EnerSys SuperSafe SBS 190F 12V - for $100 each. Or I could spend $450 on a 200Ah Lithium battery.

So I could get 4-5 AGM batteries (190Ah, 12V) for $400-$500, or one 200Ah Lithium for $450.

What's better for an off-grid solar system?

Thanks to everyone who replies!
