    Hybrid inverter downside?

    Yes. We did find some loose connections. Tightened those and let tgecsun do its thing. Turned off the trailer fridge and still had to run the generator for a while after sunset. Dropped the cutoff to 20v. Power out again this morning. Of course it's cloudy today so will probably have to run the...

    Hybrid inverter downside?

    I have an MPP Solar lv2424 hybrid inverter. 4x rich 100ah 12v Lithium batteries wired in a 23v configuration for 200ah. Sunny days here. My AC power consumption is for charging tool batteties and computer. I have a separate DC distribution box connected to the batteries for lights and phone...

    Combiner Sizing

    You're right, its 5.4amps. Was looking at the 200w sticker. Thanks for the info.

    Combiner Sizing

    I have 6x 200w, 20.4Vmp, 9.8a Imp and 6x 100w, 18.5Vmp, 9.8aImp. The online calculator for 3s4p shows that there will be 1687W, 55.5V and 30.4 amps going to the MPPSolar LV2424 once I combine it all. I am trying to size the combiner to support it. It would be easier to buy pre made but I am not...

    More 12v vs 24v system discussion

    I hope you are wrong about 24v or it is still has some years left in it. I have too much invested in 24v. The cost of keeping up with technology I guess. Thanks for the input.

    More 12v vs 24v system discussion

    Hi, I am in experiment mode on a small 12x16 shed that I have set up very minimal electrical usage in preparation for a total off-grid 600sf cabin. It has 12v USB charging ports, lights and a small 12v Cosco fridge. There are a couple rarely used 120 AC outlets. I have 2 12v Lead Acid batteries...

    24v Battery bank on 120v Cabin

    Thanks. I have a 500 gallon water tank and it does get filled up in about an hour with my Costco Firman. I definitely don't want to be starting and stopping the pump each time I turn the spigot on. The only real reason I want to go to a solar pump is to get off reliance on gasoline. Once the wet...

    24v Battery bank on 120v Cabin

    Thanks, I was at Costco yesterday and was looking at their generators. You are probably right in that getting the pump on solar would be a lot of money for the little amount I use it.

    24v Battery bank on 120v Cabin

    That is a good point. My pump is pretty deep so keeping it healthy will save money in the long run.

    24v Battery bank on 120v Cabin

    Thanks, That is great information to have before I get moving on any design changes. the Pump is at about 350 ft so it tkates alot to get going. Right now, I have a gas powered generator that does the job but would like to add to my options someday as a fall back if I cant get into town to fill...

    24v Battery bank on 120v Cabin

    I don't have the MPP Solar LV2424 specs in front of mine. Assuming they haven't changed since I bought it a couple years ago, the website says max 2.7kw output at 24vdc. I can't tell from a quick search how much wattage the inverter uses. I am using End Of life Deep cycle Lead Acid so its hard...

    24v Battery bank on 120v Cabin

    I am getting close to pulling the trigger on some 12v batteries for a new 600 sq ft totally off grid cabin I am building. I was working towards a 24v setup by purchasing the MPP Solar 24v charger/inverter with a 24v to 12v stepdown for my shed with lights and a Mini Cosco refridgerator. Works...

    12v series connect not supported?

    Thanks. That's a reason I can get my head around. Others do it so I am wondering what the decision factor is.

    24v Inverter Recommendation

    Thanks. Am in a quandary about what to do. I have $2k in parallel only batteries and $800 on the hybrid charger/inverter. I think I can find other uses for the batteries and the hybrid charger would be nice for the cabin and I can double it up for a 220Ac to power the well pump.

    12v series connect not supported?

    I am wondering why some Lithium battery manufacturers support series connecting their batteries and others don't. I found this out the hard way with an mpp solar and 2 12v big batteries.

    24v Inverter Recommendation

    I bought an MPP lv2424 and a couple big Battery 12v Lithiums. So far I am regretting it. The big batteries don't support 12v series set up so using some old deepcycle lead acid. The lv2424 turns off when voltage falls below 23v which is probably good for lead acid but a problem for Lithium. I...

    24v to 12v

    Just ordered from Hsrfington. I think I have been lucky so far with the cool weather so far. That fridge will be working hard I. A couple of weeks. (I hope).

    24v to 12v

    Thanks. I was just thinking that same thing. It is pouring rain out now so the electrical box is not a place I want ro be feeling around right now. Will check after it Dries up a bit. As I responded to another response, I have a couple lithioums here that aren't being used. I may use them for...

    24v to 12v

    I actually was just no thinking about the 2 12v lithium Big batteries that I have not been able to use because they don't seem to work in 24v serial setup. Might see about using them for DC and the MPP solar for the 120v This is a very temporary setup until I get my cabin built but that is a...

    Big Battery 12v charger?

    I have 2 12v Lithiums from Big Battery. I wanted to pit them in Series to work with my MPP Solar charger/inverter but they aren't supported as in Series. (Tried but only one battery discharged through usage and they wouldn't charging enough to stay at at 24v needed to keep the MPP solar...

    24v to 12v

    Hi, I recently added an mpp solar All in 1 24v converter/inverter. I reconnected my 4x12v Lead Acid batteries to 2x 24v batteries. That's working well. I did have to buy a 60w 24v to 12v 5A reducer for the preexisting cabin wiring Some lights, USB charging ports for my phone and a Costway DC...

    MPP Solar LV2424: 120v cycling

    Just an update. I think the cycling was caused by the batteries being below the voltage limit and the MPP not able to pull the 120v off of them. The long sunny days seem to have cured this problem. Thanks for all the help.

    Thanks. I have found other posts with the same problem. They refer to setting #4 which is not documented in the manuals I have found on line.

    MPP power saving mode

    I think I am having the same problem with my 2424LV. My manual doesn't have a #4 setting documented so I don't know what each of options means: 5d5 not. (The t is a vertical line with a horizontal line coming out st the center of it) SEN It has been a cloudy day so the batteries are showing as...

    MPP Solar LV2424: 120v cycling

    I just installed my MPP Solar LV 2424 with 4 12v sealed Lead Acid batteries. I have a 24v to 12v converter to run my existing 12v load. I noticed yesterday that when I was trying to charge a Milwaukee tool battery and then today when I was charging my computer, the power was cycling on and off...

    Cabin Permitting - Need sizing to meet Wa State energy efficiency Req

    That was the original plan. But I can't get a well permit with out an approved residential permit. I just got the permit submitted in time to beat having to buy the permit again. They would refund the original cost but the new permit cost a couple hundred dollars more. With the way things are...

    Cabin Permitting - Need sizing to meet Wa State energy efficiency Req

    I have a varied set up. A small 12*16 shed that I use for storage in winter. I uses it practice my building skills, try out design ideas and test building materials before I start the cabin build. That has 4 100 watt panels, an Mppt controller and an inverter. I don't recall the make of any of...

    Cabin Permitting - Need sizing to meet Wa State energy efficiency Req

    I am off the mountain for the winter. With the covid restrictions , I am hunkered down in small AirBnBs in middle of nowhere Montana. Plenty of time to think through this stuff. Permit philosophy where structural integrity is important for safety and any poor rescue workers who may need to rely...
