EPS BOX SP Compatibility
Good morning, I’m not sure whether the EPS BOX SP system is compatible with my single-phase inverter, model H1-3.0-E.
Thanks to anyone who can help.
Re: EPS BOX SP Compatibility
The Fox product only works with their latest generation single phase inverters (H1 Gen 2, KH)

The EPS output of the Gen 1 H1 was not particularly clean (not pure sinusoidal) and those users that needed to run on EPS for continuous periods have upgraded to the Gen 2 inverter which has a greatly improved EPS output.

There is a 3rd party product that works well with all Fox inverters, link here https://www.eco-ess.co.uk/automatic-ch ... r-systems/

Thank you for your prompt reply. I’d like to take this opportunity to ask: how can I find out the generatione of my inverter? I’m interested in purchasing and having the EPS BOX SP installed.

Many thanks

If you check the model number on the inverter label (found on the right hand lower side of the inverter), it will show either H1-3.0-E for gen 1, or H1-3-E-G2 for gen 2.
