Im trying to figure out if we are making the jump to LiFePO4 right now. We need to replace two of these: https://usbattery.ca/product/us-agm-250/
They have served us for 7 years of light duty but they are done. Basically this is a 12V 260ah bank. If I went out and replaced these today I'm...
OK, so I don't have a HUGE amount of experience building battery banks but this is a pretty basic question as it relates to SLA batteries.
For context, I have built a DIY LiFePO4 24V battery. I top balanced all cells in parallel as per all diy writeups. The concept makes sense to me. I...
So here we are......

If you zoom in directly on the pin point that's my shed with my two solar panels on it. Don't let the trees fool you. We have 60 foot pines growing in nothing (they blow over all the time).
A ground rod is NOT possible here. My...
Im considering going with an all-in-one 24V. Probably a Growatt or an MPP.
Has idle consumption improved as these types of unit mature in the market?
I say idle, and not standby because I don't think, in my use case, they'll ever get to standby, or at least, very rarely.
The unit would be...
My epever is showing .2 to .3 volts over the actual voltage at the battery terminals.
Confirmed with 2 separate volt meters and my inverter. This is while everything is hooked up and charging, or after sunset and no charging.
I'm concerned I could be bulk charging for difference reading...
Located in Canada, Ontario. N0A1E0
buyer pays shipping.
100 CAD obo.
Pulled from working 12v setup.
15 amps rating. Over Current Protection kicks in around 20 amps IIRC.
Image shows a ps-30 but this ps15 looks identical.
As the title states.
Which side of the shunt does the earth ground go on for the battery bank?
I know that all loads and charger goes on the opposite side of the shunt to the battery.
I would think the earth ground goes on the battery side of the shunt for proper metering of battery though...

Theoretical scenario.
I have a 110ah drop in replacement lifepo4 battery. On it's spec sheet it's low operating cut-out is 9.6volts. I am assuming in this scenario that the BMS will go into protect(sleep) at 9.5V.
If the battery goes to sleep, I think this may be an issue for my scc. I...
I currently have 2 x 130Watt 12V panels that I want to upgrade.
I have an Epever 4210AN 12V/24V 40 AMP SCC and a 12V LiFePO4 110ah battery
Max PV Voltage is 100V for the SCC.
@ 12V the SCC is rated for 520W which is 43.3 amps but I can over panel to 780Watts which is 65 amps as per the...
I am under the impression that all AC and DC bonding points be connected together including but not limited to:
Everything on the DC side such as the PV panels, charge controller, inverter body, LVD, and the negative battery post.
and
Everything on the AC side including but not limited to...
