Sorry to revive a slightly old thread, but came across this searching for the same issue. I have the Growatt 3000 24V hooked up to two EG4 LifePower4s setup setting 05 set to LI (05) so the AIO is communicating with the battery BMS. I noticed that once my battery gets to 100% that any loads...

I just had this happen as well. On a trip so no option to reimage until I get back. Anything else I can try or is the only option a reimage?

If it helps, here is what SA is reporting for battery voltage. The peak is at 28.4 then it slides down to 26.4 - 26.6. Is this normal / expected?

The subject pretty much sums it up. I've been running my 2x24v EG4 batteries with my Growatt 3000 24v AIO for the last year or with the BMS comms connected, but recently expanded my array and so have been taking a closer look at the data coming off the system via solar assistant and am...

Sorry - was wondering about hardware specifically. Probably run Home Assistant with Mosquitto added on.

OK, here is v2 based on feedback so far. Big switch is to something more solid state. Not quite comfortable with getting down to the component level (i.e. mofsets), so paying a little more for smart components (Shelly smart relay) to get this up and running. This seem reasonable or missing...

My plan is to feed the heating element with 24v so a 600w element would need 25A. I’ve dabbled with arduino but mqtt is all new to me so going to dive into that end of the pool. This is half the reason I love these projects! (Other half is free energy from the sun ?)

Solid call on where to put the thermostat. Redoing the diagram to reflect. What's a snubber? Any links to the PV MPPT Product? Would it be something I would switch to manually or leave in the circuit path and it would figure out when to activate?

Solid point on the potential for an oscillation. I know the voltage relay has a timer function. Wondering if I can use that to delay the opening of the circuit until a voltage drop would have recovered? Will dive into the doc on it and see what's possible there. I have the inverter connected...

Ah thanks for the tip - will look to see what the concerns were. Any other better DC thermostats you know of?

I am a few weeks away from adding another 1kw in panels to my mobile system, which will give me 2.6kw total. I will wait to see what the system production looks like once everything is in place, but there have already been a few days where I am generating more energy than my batteries (10kwh of...

Looking for a simple 24v based solution for keeping my two 24v EG4 LifePO4 batteries over the winter in my skoolie. Anyone try these? Thinking of two each attached to the bottom of each of the batteries run out of a thermostat that comes on at 35 and off at 45. 4 PCS Film Heater Plate...

From what I understand lead acid can accept and provide a charge over a wider temperature range than lifepo4 but not really a solution I need since I don’t need to really use the system when it’s cold.

Yep lifepo4. I have a battery disconnect wired to the positives I can throw as well - good call.

Starting to get cold around these parts and checked on my mobile system a few days ago and sure enough one of the low temp sensors had tripped on my eg4 lifepo4 batteries (good to know it works!) and the battery had stopped charging. I looked into heater mats and all but it occurred to me I...
