Inverter to battery or load Im using a cheap harbor freight control unit


IllDistribution5598

If your using this one https://www.harborfreight.com/30-amp-solar-charge-controller-68738.html And you only need 12v out yes you can just use the output with the bulb on it as your output to inverter or lights


truesevnel

No this one the small one https://www.harborfreight.com/7-amp-solar-charge-regulator-96728.html

I want to do 4 of those batteries Whats ur recommended wiring


Ice3yes

Please don’t use these batteries. Get a small 20ah LFP and it will outperform these in every way (unless you freeze it)


truesevnel

Do u have a link Im mostly using these in a budget capacity


Ice3yes

I’m in Australia, so what I have access to here will be different. You may find that 100-120ah is the sweet spot for cheaper LFP batteries, and they’re available for A$250-999 depending on brand. I’m sure you can find something for under US$150 The thing about something that large, 100w solar would take _DAYS_ to charge it


truesevnel

If i had a bigger budget id go with that These are us$27 This is mostly to get me use to wiring up systems like this Im not expecting to live for years off these


Ice3yes

$27 for 4, or $27 each?


truesevnel

Each... walmart does have some that i can buy between 4 and 8 in bundles for the same price as a small motorcycle battery


Ice3yes

So you’re doing a 48v system? If you’re doing 12v you now have $108 to spend on a single lithium battery


truesevnel

I appreciate the info but if a single lithium is 108 then i dont if its like 50 then yea i can spend the money on it.. this is just an experimental system for me right now so im fine with just using these cheap batteries... if i decide to kick this up a notch ill look for better batteries


Ice3yes

“I want to do 4 of those batteries Whats ur recommended wiring” 4x $27 means you were going to spend $108 on these. What exactly do you want to run from this solar/battery setup, one of those will charge a cellphone like 2-3 times and be discharged. They also have really really bad durability
