et112 energy meter with 120v

im in US so i have 120/240v power, I have a grid tied 48v quattro system to provide backup to critical loads + solar array which produces a lot more power than my critical loads need, i wanted to add et112 energy meter at my grid input and push power back to other loads but not the grid (seems pretty standard setup) so i ordered et112 + usb serial cable, it got here and on et112 it says 230v not 120v, manual states av0 part number is for 230v and av1 part number is for 120v, problem is that i cannot find this av1 part numebr anywhere, victron only shows one model number and doesnt specify voltage just amperage, so will 230v part number work on 120v system or do i need some special part? anyone can help i would appreciate it

thanks

Hi @audreez ET112-DINAV11XS1X is the part you have to search for. Victron only sells the 230V version and It is not suitable for use on 120v

I am in the same boat. There are RS485 converters for arduino so with a little programming I believe we could get a current sensor and spit out rs485. Is there a spec on what the Cerbo is expecting from the ET112?

I'm in same boat. Ordered and installed and didn't understand why wattage was so low. Nothing in website descriptions indicates voltage, can only be found in the manual if parse out the model number. Now I'm having hard time finding the 120vac version.

I am also caught by this, slightly different question if my PV inverter is sending in 240v can I use the meter or will the watts be skewed by the voltage difference ?
