FoxESS Community - Owners & Installers Forum

I’m planning on buying two additional slaves for my ECS2900 system - currently have master and single slave.
I’ve found a guide on here which shows how to do it (thanks) and see I need to make sure I buy V1 slaves.

Are there any recommendations for suppliers and any to avoid? Also what’s everyone’s experience of expected costs?

Hi I also have a v1 setup, It seems the v1's have gone out of production now unfortunately and second hand / old stock is the way forward. Ive just joined the forum hoping to locate x2 v1 slaves as for cost they were between £850 and a £1000 new i believe. good luck

After loads of looking around I’ve given up.
Easiest solution is to change your master to a V2, then you can apparently run a mix of batteries.

But cost wise it’s likely cheaper overall to move away from the ECS range and go for a newer fox battery setup.

Im now at the point where I’m just going to stay as I am and upgrade the batteries to a different range at a later date
