Wondering if anyone has any experience with a product like this from China? Was considering building another 280ah battery to increase my capacity to 560ah but came across this https://m.alibaba.com/product/1600148488856/China-Manufacture-Solar-Energy-Storage-Deep.html

Pls reach out

ok so im running a victron multiplus and overkill solar bms paired with a 4s lithium battery , its stating to get hot , so i started running the ac in short bursts but the wierdest thing is happening , itll shut down and the BMS is claiming "under temp shutdown" or whatever , as in its too...

Hey everyone, this compartment used to have a plastic box in it which was supposed to be held specifically for the battery but it took up more space and there was space outside of the box under the basement of the camper, I ripped out the box and I have been able to package my multi plus, my...

I’m upgrading my original battery cables from the two AWG to a 4/0 cable because I just installed my multiplus, can I run the 4/0 cable directly off of the battery terminals from the south itself? The battery cover and case is a bit big and I’m moving things around thanks

resolved

OK so I installed the multiplus a couple months back and it’s been working great, charges my battery really fast when I run my generator and all the 110 V circuit are working properly except for the microwave. I have 120a bMs , the microwave is pulling more than that so it shut down How can I...

So I have 4/0 between the multi and my busbars but I only have 2 awg from battery to busbar , do I need to upgrade that too?

Ok so I tested the microwave with a 3000w multiplus , got a low battery alarm and it shut down. Currently at 12.9 volts with approx 30% SOC The cable in place is not to spec, I have 2 awg cable between the multi and the bus bars but it should actually be 4/0. (Ordered) When the microwave...

Question, so if I have 5 panels in series , combined open circuit voltage is approx 105v (so I had to get the 150v mode) at a max amps of approx 8a But the max SCC output is 35 amps, is that at the array? Or the max output to the batteries ? Because this array can do closer to 55a-60a to...

Is it possible water damage seeping into a poorly crimped mc4 connector could make its way 25feet to a SCC and damage it?

Ok so I wanted to test my PV array , I had the wires from the array coming into a double pole breaker , then to the SCC , then to another breaker before the busbars I took the wires out of the breaker and put my leads of my multimeter on the bare wires , that didn’t feel exactly safe...

Ok so there are some grounding wires and other electrical junctions and connections in this plumbing box, it’s literally the only space I can put this multiplus, should I be concerned about it shorting if it moves around the box and touches anything electrical? How can I protect it? Also...

Yes it’s turning out to be one of those days, I posted in another thread about my installation issues with my recently purchased used multiplus But since I had some downtime I decided to reconnect my solar panels and get some power for the day while I wait for my mk3 adapter So I...

Hope all is well Installed a 12v 3000w multiplus , connected all the wires up and I’m getting a “low battery” flashing led , the voltage at my battery is 13.3 and the SOC is 97% I also installed the ve smart dongle and that’s stuck on “initializing” , the inverter or charger will not turn on...

Hey guys so ive been doing a lot of upgrades to the RV , Currently i have a simple inverter with no ac hardwire capability , i want to upgrade that and hardwire my main ac panel to the inverter so that all my ac loads are ready to go at all times. * I have a single phase 30amp service , 45a...

Hi guys I hope all is well, I was hoping you could help me out with this. I’ve been on the hunt for a good inverter charger for the last couple weeks and I came across this unit. All the specs match up nicely with my system the only thing that’s confusing me is the split phase. I’m looking at...

Hey guys I’m a little confused about some thing, a few weeks ago I attached five panels and series and exceeded my max voltage on my charge controller, I got an error on the device, and was not able to use it. Someone mentioned to me that it’s recommended to be slightly “over paneled” But...

Hi im confused about this product and whether I can use it for my application , this is an old style phoenix victron mutiplus. I have an RV with 120v AC , I noticed the ac input and output for this inverter are 240v So I take it this cannot be used with my current system? Or is there a way to...

Anyone selling ? pls let me know - thanks

Seems like all the panels made for RVS are a lot smaller for obvious reasons but what are the pros and cons to using something like this instead? Was thinking of adding a panel to the side of my RV that I can retract like an awning. I could potentially mount it using j brackets and have a...

Ok guys hoping I can get some of your opinions on what’s going on here A few ago weeks I upgraded my solar system on my truck camper and added a couple panels I installed 4 panels in series with a total voltage of approx 85v , the max amperage is approx 9a (the lowest of the 4 panels) I am...

Hope all is well, I noticed some erratic voltages early this morning when the sun was rising and also now again as the sun is setting. The voltage did seem to stabilize itself during the day when the sun was overhead. I took a screenshot, any ideas why this is doing that? It’s a victron 100/50...

Hope all is well I currently have a solar array on top in my truck camper which is configured in a series configuration of four panels with a total voltage of approximately 84v at 9amps I would like to add one additional panel to this configuration, a series configuration would have been...

Hope all is well , I have a 12v 280ah pack with a 120a bms i want to add another 280 pack to double my capacity i understand that i can wire the cells in parallel but im having a bit of confusion about the bms i assume i will need another 120a bms , whats the best way to wire this up? am i...

Hey guys Installed a renogy 60a with a 250amp alternator When I first turned it on I saw close to 60amps , it started to reduce down rather quickly and seemed to settle around 40-42amp Any idea why it’s so much less than the rated 60a ? Thanks

Hope all Is well I am using a muti meter and testing a series configuration of panels Currently reading 84 volts on the panels with the multimeter but the Victron MPPT is only showing 60 volts on the app, any ideas why? Could it be a loose connection somewhere? Thanks

Any idea why this is happening?

Hey guys, something doesn’t look right here The amps coming from the solar should be more than what the battery current is yes? At least that’s how it was on my old PWM controller Also, there isn’t huge discrepancy in battery voltage

i already have one DIY battery pack that i made , but before i buy another 4 cells from china i want to see if anyone has any cells they dont need thanks adam

Hello everyone , i have a truck camper, currently 400w of solar , a 30amp pwm SCC , 1000w inverter independently connected to the battery and i run an extension cord off that to run my ac devices. Everything about my setup is working perfectly for me except that amount of power im bringing in...

Updating original post : looking to add a 5th panel Currently I have below x 2 Output power 190 W Rated current 9.45 A Rated DC voltage 20.4 V Open-circuit voltage 24.09 V Module efficiency 21% Connectivity MC4 connectors X1 Maximum power (Pmax) 180W Voltage at Pmax...

Hey everyone could use some help my battery has died on two occasions where the BMS was showing my I had substantially more amp hours left any idea on how to fix this to get some more realistic figures ? Here’s a screen shot of my capacity to add to this confusion, my gopower SCC is...

Hope all is well. Two days ago I posted here https://diysolarforum.com/threads/confused-about-drop-in-amps.23088/ Regarding a drop in amps I checked the panels and connections as instructed but I think I have discovered the issue I use the BMS XiaoxiangBMS APP on IOS to monitor my battery...
