Hi, this may have already been answered elsewhere but I'm struggling to find a definitive answer. A very simple question really. Using the EPS in method 1, with a single or double socket outlet, do I need to provide overload protection for that circuit? With a 2 gang socket I could draw 26amps ...

This is a fairly basic automation that operates on a "set and forget" basis. Hopefully this will help you guys out there who - like me - sometimes forget to turn off the force discharge cycle the next day! How does it work? Savings Session Card.png 1) Enable the automation (if not on already - you ...

Thanks Ryan. I am getting this error now seems like it's not liking the code above maybe? It looks absolutely fine, it probably down to the way you've place this sensor within the config file itself. It's very touchy and in my opinion, quite annoying! It seems to me like you may have inserted lines ...

Thanks Ryan. I have a separate sensors.yaml file and get this error when doing a quick reload: Failed to reload configuration Cannot quick reload all YAML configurations because the configuration is not valid: Invalid config for [sensor.template]: expected dictionary for dictionary value @ data ...

Thanks for this guide can't wait to get it setup. However I stuck on Step 3 where you mentioned about setting up the sensor yaml template. Please can you help with how and where the files are meant to reside? Thanks Hi there! The yaml code needs to be inserted into the configuration.yaml file which ...

Someone on the group asked if I could share my YAML for the overnight charge automation I built. It's made up of a custom sensor, two input number and 3 separate automations. How does it work? Well in a nutshell, you choose a target SoC level that you want and when the set time arrives (usually the ...

This is an automation I put together to monitor the current export price and if above a certain value (and a few other conditions), it trigger the inverter to export excess to the grid. I am on the Agile Outgoing so whenever the prices is above 15p, I want to inverter to start exporting as a ...

Hi guys, do you have any info about the "UpsOutput" setting? Nothing written anywhere in publicly available fox documents. However in general UPS is faster at switching over from the Grid AC to the EPS output (<20ms) than just the EPS on it's own. This is usually only necessary when you really need ...

Thanks so much for this guide it’s working at the moment for us on 5 x v1 hv2600 and 3 v2 hv2600 batteries on bms 2 on a hybrid h1 5.0 inverter only had the v2 batteries fitted since Friday and noticed this problem on Saturday when the sun started shining the Soc got to 49% and had the problems d ...

I have been trying to do research on the external EPS using as you describe an 'auto switch', it has been difficult to identify products that are labeled as an automatic or EPS switch, looking through the literature provided by FOXESS on their website there is inadequate information on external EPS ...

When using method 1, do we need to add a N-E bonding? Just testing with a multimeter I can see a PD of ~120V between L-E and ~80V between N-E. When grid is connected I see the expected 230V between L-E and 0V between N-E. I’m not sure about the N-E bonding. As far as I’m aware, an earthing rod is th ...

Borehamwood and Luke - I’m so glad you’ve both had success in fixing this issue.

Good to hear that Fox have been quick to send out their own patched cables

Thanks for posting this. I have now got a V2 BMS, some V2 and V1 batteries. I'm seeing exactly these faults/errors, i.e.: Communication Fault Between battery and Device Bat Voltage low Bms Hardware Protect Looking at the cables used for the RS485 ports, can you use a standard ethernet cable as a ...

Hi Graham, I’m sorry I didn’t see your message, for some reason I’m not getting updates on this post.

I’m glad you sorted it and that it works for you!

Thanks Lingford, I’m glad it was useful to you. Can I check one aspect of the article please? You advise that you have a buffer of 15%. Does this mean that your SoC is 25% (being 10% minimum + 15% buffer) or is the SoC simply set to 15%? I have my “Min SoC (On Grid)” set to 25%. This minus the “Min S ...

What is EPS? The Emergency Power System (EPS) is the method of using power from your Solar Batteries to provide electricity to either a socket, a group of circuits or your whole house in the event of a power cut. How you choose to set up your EPS along with the appropriate settings will depend ...
