Upgrade L1/L2 30 Amp to 50 Amp

Hi, I have one of the discontinued L1/L2 models that looks like this: I guess it's a version 3? The firmware is 3.11.3 Can this be upgraded to the current, 50 Amp L1/L2 EVSE just by swapping out the relays and fuse box for the Struthers & Dunn contactor: ? I already have 6AWG on the input and J1772 wiring.

Yes, The 50A L1/L2 relay is compatible with all versions of OpenEVSE.

I would recommend the option that includes the Relay, connectors and QC wires as it includes everything you will need for the conversion.
