I better understand now. Thanks for the replies.

I have had my back-up system installed on my house in Austin for about a year. Rich Solar 1600 watt 24 volt system with 60 amp controller with (3) LiTime 200A 24v batteries. When my batteries are full my solar controller screen does not show how much solar my panels are producing or are...

Rich Solar replied. Bad fuse all they said.

I think this may have been the problem. I checked closer with the fuse and saw that it had arcing marks all around it. The fuse holder had corresponding marks on the the locking tabs that hold the fuse in place. No other marks on the ends of the fuses or elsewhere were noticable. I think the...

How could there be a current going through the in-line fuse from the solar panel get to be more than 30 amps and blow that fuse? I am a novice at this and is a bit puzzling. Don't understand what the function of that fuse would be if the panels could never exceed 20.4 amps with 10 gauge wire...

If my batteries have reached 100% full during the day and I put a load on the system does the controller now only send power straight to the inverter and bypass the batteries? If so, is it possible that the load if it were say 30 amps or so would that cause the 30A inline fuse on my panel array...

Thank you, so my 30A fuse is appropriate. Can't figure why the fuse blew.

Discovered that I had a 30A inline fuse that blew. lt was connected inline on the postive wire from panels on roof to controller. I thought it was a 15A but not. Put in new fuse and everything seems to be working okay as it was previously. I bought the 1600 watt 24volt solar kit from Rich...

What scenario would cause my in-line 15 amp fuse to blow that is on the positive line on my roof from my panels to my controller inside the house?

My system has been up and running for a few months with no problems. Noticed this morning that the controller does not show any input from the panels on the roof. From the on/off switch I took the two -/+ leads coming down from the roof from the panels and tested and only showed 2.3v. Should...

My 2/0 wire is 105 deg C rated. Please how does that change the figures. Thanks

My 2/0 cable is rated from -50C to +105C. The manufacturer of my 2/0 cable, Windy Nation, states it is rated for 325 amps and temp rated from -50C to +105C. My total draw on my batteries through my 24 volt 3000w inverter is about 2800 watts if everything is turned on all together. Was...

Wasn't sure about the 300A fuse all along. I am now trying to decide on going with 175A or 200A. I am fortunate to have been able to shut down the system in time. From the posts above am convinced that the way I had the stack with the nut in between the two lugs was the problem. Shudda known...

Am a novice. Read lots lof stuff trying to figure the correct fuse (battery bank to inverter) for my system and still not sure. Sorry. I have a solar back up system for my house. 1600 watts solar panels on the roof, (3) LiTime 24v 200W batteries in parallel. 24V Giandel 3000W inverter with...

okay thanks. Will get the blue Sea T class fuse holder. Want to make sure I get the right T class fuse. What would be best slow blow or fast blow? My system consists of (3) LiTime 24v 200ah batteries in parallel. 3000W 24v Giandel inverter. On the inverter it says 24V 150A input and 3000W...

My system has been up and running perfect for 2 months, no problems. This morning when throwing a switch on the transfer box that had my under the sink hot water heater in line the 300A slow acting fuse melted and caught the 2/0 wire insulation and the fuse holder on fire. I heard the inverter...

Thank you. My system is mostly a backup system for my house in case the grid goes down. I am using it a little on sunny days to run a couple freezers and refrigerator through my transfer switch and some nights which only takes them down to 80-85%. Most likely willl never fully discharge the...

Yeah, I just discovered that. Thanks. (y) Guess I got more juice than I thought.

Well further investigating and looking closer at the specs it states the voltage of these 24 volt batteries is 26.5 which is the nominal voltage. So 26.5v times 200ah equal 5120 watts. So when figgering how long my batteries will give energy to my stuff do I use the 4800 watts figure or the...

I have (3) 24 volt 200ah batteries from LiTime. Very pleased with them. Paage on their website states that the usable energy from one of these batteries is 5120 watts. I thought Volts x Amps=Watts. So wouldn't this be 4800 watts for one of these 24 volt batteries? How do they get 5120...

Thank you sir. I think I now understand that math stuff you shared in the link. Basically with the way I was gonna set it up my middle battery would have been the step child and got the crumbs. I will proceed with the smaller bus bars set up(y). You have been most helpful. Thank you...

One last question. Do the neg. wires from the batteries to the bus that are all the same length, have to be the same length as the positive wires that are all the same length from the batteries to the bus bar? Thanks

Okay do you mean like this with the smaller bus bars with 4 lugs? I am using 2/0 wires so might be challenging. Thanks for your input. Is most appreciated.

Does the cable lengths from the charger to the bus bar need to be the same length? Thanks

Phew I read that. My head still hurts. I am electrically challenged of sorts. So do you mean like this.

I was thinking on getting bus bars the length of my batteries like those that Will suggests in his video like in my drawing.

I like the bus bar setup. Can someone give me a link to where I can get the appropriate bus bars for my system. My LiFePo4 batteries are just off the floor side by side length wise with the neg. and pos. terminals all at the same end and up against a wall. Bus bars would be mouned on the...

okay, thanks again.

Thank you. Will the batteries be damaged daisy chaining them. My cables are all the same length on the batteries I already have. It looks like when I install the third battery the positive and negative cables will still all be the same length from one battery to the next.

I have two LiTime 24 volt 200ah batteries that have only been in service 2 weeks and are connected parallel. Am thinking on adding a 3rd battery the same as the other two. First is there any reason that I am not aware of concerning connecting this third battery parallel to the others that...

Is it better to have my 300 amp fuse installed closest to my 3000 watt inverter positive terminal or to the postiive terminal on my battery bank or does it matter? Photo is of the proposed wiring for my 24 volt house backup system that is being installed in my workshop. 1200 watts solar...

Thank you. Here in Austin historically we haven't had that many regular power outtages so hard to justify keeping inverter on 24/7. My electrician guy had origianally suggest manual switch. Understand about the large load start up. Would include that in my instruction sheet for transferring...

Thank you. Hadden thought about the inverter having to be "on"all the time. Perhaps I will go to manual switch and just provide an easily interpretted instructions sheet and diagram so wife can make the transfer back and forth...an' so I won't forget either. Will have to ponder this a bit more.

I have put together a back up system for my small home basically consisting of 1200w solar on roof. 60a solar controller (2) 24v 200ah LiFePo4 batteries. 24v 3000w Giandel inverter. It is enuff to run the stuff I need for a few days even if the sun don't shine. Am looking for a way so that...

I thought my original order for the four 12v batteries had already shipped and would have them very soon and be problematic returning them and getting a refund. However, thank you God, my request for cancelling the order and getting a refund was recieved by them just in the nick of time as the...
