Simple 120v Shorepower/Wall Charger?

[erstwild]

With the crazy fire situation completely blocking all the sun here in NorCal, I am looking to see if I can install a simple shore power/wall charger for my battery system. Just run an extension cord to a 120v outlet. I have a 300ah LiFePO4 House Battery I would like to charge. This new NOCO unit is exactly what I think I am looking for but not available yet:

NOCO Genius GENPRO10X1, 1-Bank, 10-Amp (10-Amp Per Bank) Fully-Automatic Smart Marine Charger, 12V Onboard Battery Charger, Battery Maintainer and Battery Desulfator with Temperature Compensation https://www.amazon.com/dp/B08G3M697M/ref=cm_sw_r_cp_api_i_OIUwFbR9CK77P

Any other recommendations?

If you have a solar charge controller on the bank like I'm thinking, since you mentioned the sun, you can just get a (whatever voltage your charge controller accepts) charger or power supply and sub that as the PV input.

I run a Mean Well SE-600 24v 25 amp 120v power supply and feed that to my Victron MPPT as if it were a solar panel. I'm in the middle of moving and had to take the house battery out of my truck weeks ago to free up bed space. It's still just sitting in the garage always full because of the Mean Well. I actually connected the power supply to a smart outlet and set a schedule so it's on at 7am and off at 5pm at a somewhat low charge current. Gives my BMS more time to rebalance my cells, something that won't happen if you leave it plugged in 24-7 and the MPPT is just maintaining a floating state of charge.

I'd do this way before I bought a special charger, especially a (bound to be) pricey NOCO at only 10 amps. All of the settings I know work in the real world and keep my lifepo4 where I want it are preserved. 24v chargers are cheap and plentiful and the process to switch from wall to solar is as easy as the plug you install (or already installed). Anderson powerpoles make it 2 seconds. My cc maxes out at 15 amps / a little over 200w so I didn't need the 600w power supply but I do have a 30 amp hobby charge controller/balancer that I use from time to time.

Noco’s are cheap and work well.

I use an IOTA DLS-45 (though a lower-amperage one would likely be sufficient for most folks - the 45A was needed when I had the Odyssey batteries that required a 1/2C charge rate).

Mine is mounted in the rig and I use one of those body-mount shore-power sockets so I can just plug in an extension cord in the driveway:


(But you could also just feed in through a window gap or under the body, etc.)

Doing it this way both charges the house battery (and starter battery via the split-charge relay), but also supplies 12v for the fridge, etc. so I can pre-cool the fridge before trips without killing the battery. I've also been doing this to run the fridge full-time while we're in COVID lockdown - I keep extra veggies, etc. in there!


The IOTA chargers use different plug-in IQ4 charge modules for each battery type which is nice. When I originally bought the power supply, Lithium batteries weren't readily available in large sizes, but they've since released a LiFePO4-capable module so when I switch from AGMs to Lithium, it's just a $20 module change and I keep the same shore-power charger.
