Just wanted to confirm the HV2600 batteries and BMS came new from a fox supplier right? If it did then I would contact your supplier and if required foxess support.

I would email direct using that address, others have reported no issue when using this address for support.

if combine they're at 50volts and they should be more like 100ish volts this is likely why the system is dead. I bet it's expecting 100v minimum as it requires 2 battery units.

Battery awaken breaker should be turned off and the cover should be closed flush with the bms.

Just to check, you've emailed service.uk@fox-ess.com correct?

Good call on the data driven decision, home assistant will clearly show you how much battery/solar and grid you're using. On the battery side, there is no formal requirement that you install new batteries within a year, it's simply best practice but you could technically install more batteries in 2 ...

Can you upload/attach a photo of your full setup?

Hey, On batteries - you can technically add batteries at any time but the larger the delta in new vs old batteries the worst perfomance you'll get, it's noting worth losing sleep over however. It's recommended to installers to scale within the first year if possible. On solar - Inverters are limited...

FoxESS like many inverters have MPPT solar features which is Maximum Power Point Tracking which can alter panel efficiency to match demand and capacity of the inverter. I believe the unused solar is converted into heat by the panels and inverter. Regarding what size battery you would benefit from. I...

Hello, On the inverter sizing, yes it's best practice and normal to underrate the inverter slightly vs the full possible panel generation potential value. The panels will normally only generate their rated wattage in lab conditions so in the real world they'll perform slightly worst. Inverters have ...

Super thanks

Agent accounts have the firmware updater which sends and installs updates over the cloud via the wifi module.
If you're not an agent you should speak to your installer or contact fox support.

If you've noticed that your inverter is not sending data to the FoxESS cloud or that your inverter appears offline on the app but is working fine follow these steps. IF YOUR INVERTER HAS NEVER REPORTED CORRECTLY ENSURE THE FIRMWARE IS UP TO DATE AS THIS IS A COMMON ISSUE. 1. Is the wifi module flash...

Can you upload a photo of the BMS? Normally HV2600 are around 53volts. 20 voltages sounds like permanent damage has occurred. I assume you have the BMS connected to an inverter right? then you set the dip switches to the correct dip position, turn on the main MCB breaker and then press the silver po...

Hello, I would be interested to hear what FoxESS support come back with but all my installs are the same. I believe it's all to do with BMS calibration and how tricky LifePo4 batteries are to gain a true SoC. Whats likely happening is the missing capacity is either not being used and when it states ...

The Mira HV25 is a new high-performance, scalable battery storage module product by FoxESS. It appears to be very similar to the HV2600 The modular design allows for maximum flexibility, making it suitable for a broad range of storage applications. Additional batteries can be installed in series, al...

As no V2's have yet landed in the UK, it's 99.999999% likely you have a V1.

Great work, nice one!

Hey @Ibuk,

It's not required for end-user registrations or installers who are not top-tier partner installers. Just leave it blank if you haven't been issued a reference.

Screenshot 2022-10-16 091207.png It's pretty common while there are long delays on battery installations for installers to install just the inverter, which will act as a solar inverter only. The downside of this is that it leaves you with a nasty BMS COMS LOST error and a red flashing error which i...

My fox contact recently confirmed that remote flashing won't work and a V2 BMS will be required. If you have a different experience we'd love to hear about it.

H1_Manager_V1.49 released but no noticeable changes to features or settings.

yep, that is spot on what I do when upgrading customers batteries. Cubes just make it easier as you don't have to mess around with brackets and cables. Please post pictures once done or get someone to record you upgrading it so we can create an upgrade video to help others.

Yes, 100% than a shelly, the frient doesn't even get warm and it has internal safety measures including temp sensing to protect it so I sleep well knowing it's a solid bit of kit.
