Modbus Single Phase, Electric Energy Meter - Electricity Meter to Measure Low-amp Circuits - Pulse Output 1 1000imp/kWh - RS485 Modbus - SDM120-MODBUS-MID

Works great and is very accurate. Straight swap for the older 45 amp model.

Worked perfectly and added this to my DU box.Connected when configured to work with my sunsynk eco 8kw and has no issues with zero grid feed setting.Always use a qualified electrician electricity can kill.

I fitted this to sub-meter my business workshop, which is supplied from the house consumer unit. I housed it in the workshop CU - a really easy fit as this unit has a good quality locking slider for the DIN rail. Just remember you will ideally want to position next to the main switch/rcd and alter the live busbar such that all the breakers are fed from the live out out of this unit.

Does what it needs to as a meter, and is a good fit in my installation. In my case that's in the consumer unit in an outbuilding that I wanted to know the specific electricity usage for.Fitting was OK, but per the photo I did need to bend the consumer unit's bus bar a little as the screw terminal locations in this meter were staggered relative to the standard MCBs to be fed from it. The screw terminals are of course also eccentric across the meter as there are two side by side in the 1U width meter, and they're also thinner than the bus bar was. Not insurmountable in this case, but perhaps a differing standard somehow.As far as the meter in use, it works perfectly (as far as I can tell for accuracy anyway) and has been very handy.

The media could not be loaded. Installed it for my customer shop owner to seperate flats and works well. Thank you

These units are easy to fit and give a good indication of the KWh consumed through them. They fit on the DIN rail but will require the live conductor lugs cutting off. The units have cable connections in and out. They are rated to 45amps, I’m using them in supplies rated to 40amps.

Works fine with a sunsynk ecco 3.6kW inverter

Bought to cover whole load of my Static Caravan, on arrival I wasn’t happy using for full load due to terminal size and appearance. Used just for one 16A car charger circuit. Does appear to work for this. Note illuminated all the time which could be annoying for some.
