Here is the shunt attached

When switched to go through the Inkbird, it cools but at a markedly slow pace as compared with switching off the Inkbird. That said, I swapped the batteries out. The be I was using said it was fully charged but maybe that could be part of the problem. I will order another inkbird if this...

Thank you, I do see that now. I also seem to have low temp protection built in

Multimeter reads 110v in n the outlets of the inverter when it is in use

It is powered by my solar panels. It is wired to a fuse box (2amp fuse) and a neg bus bar.

a system I set up over a year ago with help from this forum has been powering a small freezer without issue…until last week. After losing a bunch of food, I discovered the freezer, a small 3 cu ft model wasn’t reaching 0. I purchased a new freezer in a panic only to discover that the old one...

For some reason, my load port is not putting out anything. I have checked the mt50 parameters and it says the load is on. Anyone know why that might be?

So, your diagram is connecting to the "load" inputs on the SCC. Is that what you intended? I have never used the load outputs on a SCC. I have mine hooked up directly to the positive terminal of my fuse box and the negative directly to the negative bus bar. I programmed my SCC to cut off...

It's not three. Its just one agm that I use when the lithium drain too low. Then I charge the lithium inside and swap out when the agm gets too low. we don't get much such here. The two lithium are just in parallel.

They are Weize 100ah batteries. According to their ad and Will Prowse's review, they do have low temp protection. Unless mine are faulty somehow, I don't think this is the problem.

How do I delete?

Right, but the same problem with a brand new freezer? Should be reaching subzero no problem.

Thank you. Totally easy to understand. Is there a reason why I need this during “topping off”? Is it in case the power supply is not accurate?

I’ve been searching for guidelines on bench charging the lifep04 with one of the 30v/10a power supplies. Does anyone have advice there?

I have a 50amp Epever 5414an I came out to the shed to find the MT50 module reading “connecting…” I tried resets but nothing worked. Hooked up a CC meant for gel batteries and got no response. Checked my fuses on the roof panels, all have continuity. The 80amp fuse in the CC is good. What...

I don’t have two simple wires going to my rocker switch. I have it all on small boards with a white multithread cable going to it. Do you have any idea which is which?

Please comment on this potential setup. I currently have: 4 100w panels 18v 5a each 150v max 40amp Solar charge controller I am considering adding 4x300w panels(36v 8amp) Please analyze this wiring layout and give your thoughts. 4 300w panels wired in parallel producing 36v 32amp 2 100w...

Would you mind being more specific with your wiring suggestion? I am going to try this.

I can’t even get to load settings on the mt50. It jumps to the “welcome” screen and then back to the beginning. I am returning the ScC. It has a defect on the lcd. Maybe it’s a bad unit. There was no voltage on the load screws when I manually turned on the load. There is a switch(very awkward...

4 100w and 2 200w

Yeah, they have protection built in. It don’t think that’s it.

I think I see what happened. I bumped the voltage as sunshine eggo suggested. And as I was reconnecting, I noticed the red clip wasn’t pushed all the way in. You can see it in the photo I posted.

So assuming I bite the bullet and spring for say a Victron charger, and then fully charge the batteries, how would I then determine whether or not they are faulty? My small setup will never be grid tied so I will need to proceed with that in mind.

Oh right. I’ll move it down then to the next where all three lines will run through it. Thanks

Do you mean the literal connections on the batteries or some way that I have things hooked together?

If there’s an open connection, I’m sure not finding it… Not getting power with just the battery hooked up to it. The inverter turns on when hooked up to the battery.

I’m not sure. Do you mean how long did I charge it for? This morning it was charged to 14.4. When I read after disconnecting, it dropped to 14.2

So I soldered it as you said and it ndeed this did preserve a lot of battery. Now, a strange thing happens. Been working as you described for a few days, now the inkbird switched on( batteries at 14v) and immediately, the inverter begins beeping and battery voltage drops to 10.4. If I shut...

Additional info: panel cables coming into CC read 46dc volts which is right But unless I am not using the meter correctly(100% possible) it isn’t giving me any amps…could that be a clue?

Right. Figured that out after I disconnect the meter. Oops. Now reads 14.1 on DMM
