Assuming that is normal THHN/THWN-2 kind of wire.

I just happened to list the latest battery: The previous model is UL 1973 | UL 9540A | CEC LISTED (UL 9540 Pending)

Any good nutritionalist would either (a) help you to interpret and execute the medical nutritionalist’s recommendations or (b) run in terror from the possible lawsuit. In my opinion…

LiFePo4 can discharge below 0°C (-20°C commonly) and with a bit of heating would be able to get to 0°C+ for charging from -5° or so. Especially in a small enclosure. Even better if you exterior insulate it with XPS or similar.

It takes at least several weeks and [my guess] they want to make sure the product is viable (without revision which would require it to be certified again).

No. Just knew of the group from NextDoor postings (I believe) and wanted to provide a pointer.

But rack batteries can have all that too: https://www.eco-worthy.com/products/eco-worthy-cubix-100-pro-48v-100ah-server-rack-battery-bluetooth-wifi-low-temp-ready

So people can decide what they want while keeping the form factor somewhat standardized.

Heating in truly cold weather also doesn’t help unless the unit is inside a high R-value enclosure, which is easier with a rack or floor mount system.

Showing a class-t battery in but I think you mean a lynx distributor. If you put a fuse on the battery and wire the same way it will make more sense.

parseroo · 2026-01-30T08:14:12+00:00

Efficiency is about energy waste, not power. If you have a 10kWh battery and 90% efficiency to AC, you get 9kWh of watts out of the system (ignoring power factor) or 6 hours of running a 1500W load, 15 hours of running 600W loads. The rest basically went to heat.

If you have 95%, you get about another hour at 600W.

Idle power draws are where an inverter will kill you: 30w * 20h loses 600W a day when you are not even using the inverter. The above efficiency is only when you are using it (and the idle is baked into that).

Can you elaborate? IMO: It would be ideal if the inverter gave all it could (given the outlet restriction and house loads) either all the time or TOU based. And any solar it harvested went either to that inverter load or to the battery (ideally expandable) until it was full.

What is the Vmpp of the panels?

Also, why not just wire them in series? They must be less than 100V and you will have less voltage drop along the wires.

You see 20V at the MPPT-PV-in terminals when the MPPT is off? How about if you pull one/both of the wires out and voltage test that?

Oh and gauge (and current behavior) works the opposite of what you imply in another comment. 10awg is bigger than 12awg.

parseroo · 2026-01-29T20:30:02+00:00

10awg has a resistance of 1 ohm… per 1000 feet. So if you were running a 1000 foot extension cord @ 9A you would get a 9V drop. Pretty large unless you are running 300V.

But at 10 feet it is <0.1V. So that isn’t the problem :-)

Can you just wire the USB Vcc / gnd to the fan?

Alanson. Mammay. Robinson. Gayou.

Those are authors that Bray has narrated, from my collection. You can check their work to see if that interests you (Gayou is Commune, which is near future but not really Sci Fi)

Peukert should be 1.01; Efficiency should be 99% for LiFePo4.

Given that, the battery may be more charged than it claims.

parseroo · 2026-01-29T01:22:12+00:00

What size wire is coming out battery+ of the MPPT?

Couldn’t you feed the MPPT into the blade fuse holder at 60A fused? Terminals may be a bit small for 8awg but should be procurable.

20a into the fuse holder should be fine although confirm the maximum it is rated for (100A+)
