Excellent to hear, so far they have been solid.

Hey, hope your doing well. What switch/breaker that you have in place between the battery and the inverter?

I just bought 2 of these as well

Interesting video. I'm just beginning to learn about solar panels and storage batteries. It would be helpful if you could do a detailed video explaining your system design & a schematic and show how it is all connected up to help us newbie's understand it. I'll be watching your videos with interest as I'm keen to learn from your experiences.

@@Wawyed Hi, yep sounds like the same issue, if the cables are in the meter correctly and it sometimes picks up a connection with the meter and it keeps dropping off then it's likely the exact same issue. I resolved mine with perseverance, bit of tape and some copper shavings in the female end (cable end) to bridge the metal not touching. have an RMA outstanding for a replacement unit.

What is the adsorption charging voltage? My inverter has 57.6v coming out the box but the pylontech manual gives charging voltage in a range of 52.5 to 53.2 if i remember correctly. Do i need to change my adsorption charging voltage?

Unfortunately the BMS information available on the inverter doesn't tell me that as it's a preset for pylontech on my inverter.

Quick question I noticed the batteries don't show SOC lights before you switched inverter on is that normal for pylontech?

Hi Colin109, I think this may have been how I operated it, but when you flick the switch they all come on and after a few seconds display their state of charge. so you should be able to tell roughly without connecting to an inverter.

I am having a hell of a time trying to find a battery with sufficient continuous discharge rate of at least 4/5kw and I was just wondering do you know how much you can get to peak before it starts splitting power from the battery and grid. If I have 20kw of storage full I dont want to be pulling anything from the grid if I want to cook dinner whilst the washing machine is on, or use an AC at night for an hour or two. I was recommended these but getting conflicted information and most batteries on continuous discharge wont state watt load just amps.

This is a combination of Inverter used and battery so I'm gonna have to assume the inverter you have or have in mind is spec'd accordingly. The 2 x pylontech US5000 are happy to put out 160amp at 48v most of the time so once again if your inverter is happy with that then two of these will do the job easily with overhead. My brothers Fox system also is ok with it. if you want me to find out what batteries he has (model no) then please let me know.

@@th3bmc That is great news, not sure why they cannot state this generally in statistics and keep throwing things off. The guy I was speaking with suggested 3 but adding an extra for just under 20kwh total when on our most hungriest month used when averaged out 28kw a day means we would be golden (Since we can use machine and dryer during day when generating when sun is out, save all the washing and whatnot for that day) More often than not we average 15-20kw so this is great. I appreciate you getting back to me, the chap I was speaking with was going to use the Solis 5kw inverter "1xRHI-5K-48ES-5G" and 3x US5000 which I would bump up to 4.

Yeah 5.2kw sounds sensible to me for a 5kw inverter maybe even less panels like 4.5kw unless you plan to export, I have 3.6kw inverter and wish I went larger now, I make it work but when and if I have kids running around they won't care to keep electrical loads under 3kw total in the evenings or winter days. It's hard for output info because it's so subjective to give advice based on location, panels used and angle ect.. Opensolar.com gives good insights into generation, you have to create an account but its free.

I just received a US5000 and tried the soft power on with nothing else connected - it lit up the LEDs and then they all went out - does the run LED stay lit or flash periodically in this state please? (I know you were trying to balance yours so it may be different)

Have you found a max draw from batteries before it will pull from grid and battery, I am trying to figure out what continuous (non peak 15m/15s loads) power can be drawn from it. Some batteries clearly state 4kw/5kw/7kw/11kw etc etc but I cant seem to find a straight answer on like 90% minimum of the batteries ive looked at they are mostly conflicting info depending on site and switch between kw and amps

@@cnjelly7876 having watched the behaviour of the US5000 over the last few months, the BMS behaves a bit differently from earlier models - particularly with regards to temperature - there seem to be more bands. However, by default when it's "happy" it will report 80A C/D to the inverter - however, it will only charge for short periods at 50-60A and then drop to 20A as it gets too hot (I think) - conversely I've never seen my 3kW inverter go above 2.5kW so I think the usual limit of 0.5C applies at 50A for a single pack and it never tries to pull more though that may be the inverter - I have been tempted to add another US2000 or even another 5000 if the prices keep dropping, but the 5000 seems to work pretty well as single pack...

Video being published tomorrow on this

Theres a lot of videos like this with people using the wrong cable. You have 2x us5000 batteries in parralel which is over 200a, but youve used the cable supplied with the batteries, which is only rated to 100a. This cable is under spec and needs to be replaced with thicker cable, or you could fix your discharge limit to 100a to support the cable. Id be interested to see a video of how people have addressed this problem as there appears to be nothing on youtube

When space / weight is not an issue regarding batteries why are people not using 4 x 12v 130Ah lead acid batteries, this gives over 6 K hr with a price tag under £400, most inverters will charge lead acid without issue.

@th3bmc

Жыл бұрын

That's a fair question, there are a few reasons, Depth of discharge, amount of charge cycles (granted it would be cheaper to replace multiple times but then there is environmental impact and waste), low Temperature effect's, The inverter supports lead acid but does put many 'scary' warnings of *experts only* all over the manual about lead acid and finally you have to buy a separate BMS and wire it up manually if you want to monitor. With these packs it's more plug and play or set and leave. *Also warranty, I had to check to see what the longest warranty I could find on a lead acid leisure battery and 5 years appears to be the max but 'Deep or Over Cycling' and 'Wear and Tear' is not covered so not worth the paper it's written on.

Typically you use half of the lead acid battery capacity, so your supposed 6,5kwh battery is essential a 3,25kwh battery, the price for the batteries you're suggesting are not AGM or gel type batteries, or even deep cycle ones, probably more like ordinary car or light truck batteries, these would be even more restricted in the amount of power you can safely extract from then while still have a decent life expectancy. Lead is dead, lithium or LiFePo4 are gonna be cheaper in the long run, you can even assemble loose cells yourself with a BMS to regulate it and put a nifty DIY rig together for less than half the price of the pylontechs, can't imagine people are still doing lead acids as it is such a ancient technology.
