wrong item send. after communications with seller, fast send another item. still in transit, so no feedback about product
good item. works perfectly with solax X1-5.0-T-N (so should work with the others from same series). when wired into the inverters meter port it allows inverter to read export/import energy etc and also automatically uploads this data to the solax portal monitoring website if you have the inverter/WiFi dongle configured. you do need to set the inverter to "export control" or the inverter doesn't read the data from meter - but can just set the export control at 20kw so it doesn't actually impact the export power.
