I have now tested the one I believe to be the least capacity cell, because it's the one triggering the low voltage protection when the pack is fully discharged. I did not test this cell when new, so its original capacity is unknown. Its current capacity is 263.30 Ah, 847.58Wh (test conditions...

Yes, they work great! I no longer see a pool of water on the bottom of the panels

Having started look into something similar, do you know the cell chemistry and number of cells of your mower? Mine is also 82V (cramer) but not sure about chemistry and number of cells

Because I intended to use its 230V charger, which means I need an inverter (which needs a battery). Not sure if the proprietary connector would accept DC voltage from any solar charge controller (do they even exist that can provide 82V?) The land is 4-5 hectares.

The only reason I see to have a bigger battery is to take advantage of solar production grater than the power that the mower’s charger is able to deliver (let’s say 2kW) Or for taking advantage of the early morning production, where the peak power hasn’t yet reached the mower’s charger power...

I have an electric zero turn lawn mower with a 24kWh battery. I also have a small shed where the mower can stay when not in used, the roof is about 4m x 3m, enough for 2.4kWp (I don’t think I need that much). I was making a consideration; the lawn mower is mainly used in the summer because is...

I've finally bought another EBC-A40L and I'm currently testing the same cells I tested 15 months ago. They have since been cycled 224 times. I'm using the same logic as before: charge to 3.65V with cut off current of 5A, wait 30 minutes, discharge till 2.5V Here is a comparison of my first...

How does it work? I have setup the capacity to 280Ah, but the bms triggers low voltage protection when there are around 25Ah left, so it should show 91% SoH. Has the ‘rated capacity’ or ‘battery capcity’ displayed changed for you? Do you regularly hit the low voltage protection by any chance?

Hello, has anyone ever seen a State Of Health other than 100% on their Seplos BMS?

No, I ended up using the EspHome seplos integration for home assistant

Yes, I first bought the one from Amazon but then returned because it was becoming very hot at 50A. I ended up buying the Victron one which is much better

It does it on all power levels, but I just noticed that 50% of the times it exports (let’s say 150W), the other 50% it imports those 150W (instead of hovering around 10W)

I don’t have solar; only a battery to cheaply store energy overnight.

How can you tell they were over torqued?

I have a Sofar ME3000SP which has a CT clamp to limit the export to grid. As a consequence, I have a steady import of around 5-10W. I measure this through a different device and I receive a Home Assistant notification when it exports for more than 20 seconds. I noticed that there are a couple of...

I had the same problem a few days ago after a year of 100% reliability. It started working again after disconnecting the bms from the battery and reconnecting it. Someone on here suggested getting the latest firmware from Seplos which apparently solves the problem. Reading this discussion, I’m...

Ah ok; it still does detect small currents in the other direction though

So where does the missing current go?

I’ve just bought them; I’ll report back

No, I just found them while actually looking for panels with pre cut drains (which I had seen before) They seem to work as a syphon, although I don’t understand how they can create a completely sealed channel

Yes, exactly. It was easy to mount them parallel to the roof; I know I could get better performance by tilting them, but I prefer to keep them like this. I have thought of cutting a channel in the frame but I don’t want to risk damaging them I have seen these on Amazon, do they work?

That's the only thing I cannot change

I have mounted a couple of solar panels on my garage (almost) flat roof. When it rains there is a puddle of water forming around the lower part of the panels (the inclination is not enough to allow water to escape) and when water dries, it leaves behind some dirt. How can I avoid this?

Hello, I have a Seplos 10E which I’ve so far only connected to a Sofar inverter to charge at night and discharge during the day. I’ve recently added two solar panels and a Victron solar charge controller by introducing two busbars between the battery and the inverter. The solar production rarely...

Ok, I updated the firmware. I still get words like ‘monomer’ in the parameter settings; I’d swear I’ve seen videos where those translations had been corrected and I would have thought the newest firmware would have those corrections

I contacted Candice from Seplos on whatsapp, she sent me this file Is there any risk in updating the firmware?

I have this data from the coldest day so far (-5 deg C). I have 25mm polystyrene insulation around the battery and it's in an unheated garage. As you can see, it starts charging at 11.30PM with the battery average temperature around 6deg; the inverter is sending about 10A to the battery, about...

Why do I need a firmware update? Is this a common problem and there’s a fix?

I disconnected the bms from the battery for 30 seconds and reconnected it. It now works again, I can see the data in Home Assistant. What could have happened?

Well, sort of. I placed the 4 sensors on the outside of the cells at mid height, two on each shelf, on the 2nd and 6th cells of each row. I have set the low temperature protection very low (I think -10 deg C), this is because below this the BMS won’t charge but also won’t attempt to heat the...

All in the off position, I haven’t changed anything via BT recently

I tried pressing the button on the bms until it turns off and then turning it on; or do you mean disconnecting it from the battery?

Hello, I was happily monitoring my Seplos BMS in Home Assistant using esphome https://github.com/syssi/esphome-seplos-bms It stopped working a few days ago showing all entities as unavailable; I spent days trying to fix it on the Home Assistant side with no success. Today I tried using Battery...

Could it be than when I slide the rubber bit over the crimped connector I am bending the metal teeth enough for them not to grip? I have tried to remember to do it before and that one seems to hold
