Lithium Iron Phosphate Battery technology - off gride

Q5: Welcome to Off Grid living.

Update to April 2026 I contacted an air conditioner expert and he thinks my settings are normal for my air conditioner.

This is good news.

The Lithium Iron Phosphate battery technology is great.

Thanks to Custom Lithium

The 310 Amp/hr battery cost me $5,000

Three 100|50 Solar Controllers $800

Solar panels cost me about $7,000

The air conditioner unit cost me about $6000

So the total cost to keep a room cool was about $19,000

Seems expensive hey?

The system is to run for 10 years, and in theory saves ( 0.25 x 24 x 365 x 10 = $22,000)

So you more or less break even on the first 10 years.

On the next block of 10 years, replace the batteries, and repair / replace compressor

Estimate costs $10,000

So you end up being $12,000 in front after 20 years of use.

Shalom
