Just had a look at my MCS certificate, it actually only covers the PV install, including inverter and wiring and all isolators. The certificate itself does not mention the battery or its size. Still keen to hear other opinions on this, as there are significant savings possible.

Hello all,

looking todo a similar thing. I would like to know the impact on the MCS certificate? In theory it would not be an MCS approved system anymore and therefore in theory any provide could refuse to pay for export? Does anyone have any views on this point?

Thanks. Ah, I thought you had them split into two stacks, e.g. 3+BMS and another 3 next to it. But upright might also help to spread the load.

Mine looks like this.

Ahh also in loft then, wow.

If they have been installed front side up, did they have to build some sort of enclosure/rack holding them in place upright?

Thank you, that's re-assuring. I will let my installer know.

How many batteries do you have? Any chance you have a picture of the two stacks next to each other?

Hello all,

I currently have 3x HV25 + 1x BMS stored on one stack, in my loft. System is running great.

In the future, I am planning to swap my old gas stove with an induction stove. We cook almost every day, so I am expecting to require another 1.5-2kwh just for that. Will therefore likely add ...

FYI, I have completed this in the summer and it works perfectly fine.

Thanks for the explanation, that is very clear and insightful. I will double check, but very unlikely they will have left the CCA hidden in the roof felting. Also it appears that the CCA seems to be the most valuable part of the kit. So unless I find a used CCA for cheap on Ebay, there is no point ...

Thanks Dave. I will take a look and revert back. The system was only installed in December 2023 so I am under warranty and the installer has full access.

Another somewhat related question... during the configuration stage the installer asked me if I wanted the ability to monitor each panel ...

Thanks Dave, that is very helpful.

I was unaware the LAN stick comes in USB and original round connector (I guess it looks similar to the Meter/CT/RS485 connector).

Do I need to power down the entire system for this? Presumably the system would keep running even if I pull out the USB Dongle, I ...

Hello Everyone,

first time poster.

I have a Fox ESS H1 with 3x HV25 installed last year. They are powered by 9x Canadian Solar 430w. The system is running very well and I am quite happy with it.

The installer used the wifi dongle to connect the inverter to the fox cloud, however the signal is ...
