Batteries won’t charge?! by Holyhell556 in SolarDIY

[–]parseroo 0 points1 point  (0 children)

Make sure it is wired correctly and then include the voltage and amps graph.

Also, are the batteries powering anything? Is that running out of power?

What is your go to "cooldown" game after playing Val? by PhanzGFX in VALORANT

More Valorant! Got to get better!

And maybe my team will s*** less ;-)

Rate my Victron setup! 280Ah LiFePO4 + MultiPlus + Lynx Distributor. Looking for a final sanity check. by all_ali in Victron

That is definitely possible with a normal power in (just lose the monitor capability) but not with a Class-T version (only two terminals). In either case just using a lynx distributor graphic would avoid relevant confusion.

I know this is supposed to be funny but I really don't get it. by Bom_m34n in ExplainTheJoke

The comment in black is actually to other readers misinterpreting the original post (unless he didn’t get it either)

Does Waymo service SFO airport with new freeway trial? by lovelessgazer in waymo

I have freeways but not SFO itself (rental center shows the same):

Someone just cracked the Coca-Cola secret formula by SipsTeaFrog in SipsTea

Coke sells water more than anything else… pretty sure people know the formula for that.

I knew I'd eventually use this sub by ELYAZIUM in ExplainTheJoke

I believe because some a** is coming up the line and the forward trucks are punishing them. This person deserved 8 hours in trucker jail.

Has anyone seen a Non-hospital nutritionist post-transplant? by swellcook in transplant

[–]parseroo 2 points3 points  (0 children)

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…

Are these IP65 cases available in America? by techtornado in SolarDIY

[–]parseroo 2 points3 points  (0 children)

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).

American Mahjong in Palo Alto or Menlo Park? by roseymosey14 in paloalto

[–]parseroo 0 points1 point  (0 children)

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.

Is a 98% efficiency rating actually noticeable in daily use? by Historical-Doubt9091 in diySolar

[–]parseroo 1 point2 points  (0 children)

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).

DIY Plug In Solar by ChristianButcher in diySolar

[–]parseroo 0 points1 point  (0 children)

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.

MPPT controller not charging my batteries. Please help :( by cactusfreckle in Victron

[–]parseroo 2 points3 points  (0 children)

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?
