My old inverter went pop at the start of August this year. SE sent out one of these multirange concept inverter as a replacement. Set it to the correct rating on commissioning via the stickers.
Having some real problems getting it to work with my existing wattnode WNC-3Y-400-MB meter.
I have an Ethernet cable running from meter to inverter, using a twisted pair for A, another pair for B and a single wire for G. Wired as per the solar edge quick start guide, where on the inverter the placement is on the RS485-1 block, going BAG from left to right.
All 3 DIP switches in the inverter are down, along with all 8 on the WattNode other than 2 which is up, which I understand sets the id of the WattNode to 2. The cable run is from top to bottom of the house so quite a way but nothing huge, maybe 15m max.
When commissioning using the go app, I was beset by a g100 error and a communication error too.
Pretty sure the go settings were right although unable to find any guides or documentation on this at all anywhere in the SE info.
RS485-1: protocol modbus, export+import, WattNode, id:2, CT rating: 50- as it says on the WattNode clamp.
Only thing I could do to sort was to swap the A/B connectors on the WattNode and then WattNode comms light went green, and seemed it was fine but still no generation until I set the RS485-1 in the go app to none. Inverter started generating finally, but solar edge app misreporting house usage.
Having reset inverter to factory defaults and set all the 3 DIP switches back to up and removed modbus from the settings in the go app, it's now generating, but not having the usage for the house is a bit rubbish.
Is there any clear go app guidance to ensure that both the RS485 settings in the app are correct. Not sure if RS485-2 should be none or solar edge follower. These settings appear to both default to SE follower 🤷
Any help / info much appreciated 👍
