On-grid domestic battery storage

I must admit, that having two devices which are both trying to control the flow is always going to be problematic. I'd be tempted to disconnect the immersion controller.

Could something have switched of at 6.30 causing a momentary export before the inverter could ramp down? The Solic jumps in to grab the export & the battery responds by ramping back up again to meet the Solic demand.

No idea what would cause an export but I have switched the Solic off...

Thanks I have turned it off

Bit of battery news, but reads like an advert and seems targeted at powercuts, plus I lost interest halfway through ...... but apart from that .......

Span Partners With LG On Intelligent Breaker Panel & Energy Storage

Span, maker of the smart electrical panel, has partnered with LG to develop a fully integrated electrical and energy management system for the home. The new offering will integrate Span’s smart panel and LG’s RESU energy storage units to give homeowners unprecedented control over their energy to enable them to use it when the want, how they want.

Looks like a bit of a Powerwall clone.
Must admit, I haven't even bothered wiring up the EPS on our system
Could count on one hand the number of powercuts we've ever had.
Of course, now that I've said that .......

It's worth wiring up even if you only add a double socket to the EPS.

If i was gonna do it, id have to do it wired to a contactor so that the whole house would be powered, and disconnected from the grid or honestly, whats the point?
Double socket means, what a lamp on an extension?
My leccy box has 2 "zones" so id need them both active for all lights to be on, which essentially means powering the whole house.

Ill get round to it one day... probably a couple of days after the first powercut 😳

Nice one !  👍
What would also be really useful is code that could predict and set how much to grid charge the Pylons based on weather forecast and time of year, similar to the Powerwall.
Trying to judge this manually gets fairly tedious quite quickly.
I'm sure some smarter cookie than me will figure it  before long.

If you read the pylontech manual,  you will note that at no point does it mention any kind of air gap, and also says they can be put on their side.

Been away for a couple of weeks but thought Id come back to this.

Yes you are correct that the manual doesnt mention any air gap. The manual assumes you are using brackets to separate them and the brackets are designed as the air gap. The manual also says you can stack 4 horizontally and 2 vertically.... Read into that what you will.

The manual also says the batteries should be more than 0.5m from the inverter heat output.. I dont know what the distance you have is from the top of the inverter.

You look like you have enough room on the shelf to put a bit of an air gap between the batteries. May do nothing but cant hurt and might prolong the life of the batteries somewhat.

Skimmed through the last 2 weeks posts and someone mentioned operating temperature. The pylontech techincals say around 25C/26C (IIRC dont recall exactly) for optimum operation (which isnt the operating range) so whilst maybe not much appreciable difference, like the air gap thing mentioned above in or around 26C ambient will be the optimum for operation/longevity etc.

We will only really know (as with any battery product) in 10 years time whether the specs were right or not.
