Modbus Profile Mapping to SolarEdge Inverter

I've attached a tested / validated example json for you to re-work to other items . I use it often as a base template.

it covers various types including bitmask alarms where the same modbus register is used to report different alarm states, should have some more dcos to share later, but , many have said, json is a very hit and miss affair that rely's on having the product to test.

even then many manufacturers may not provide the easy information, ie... for when its not a "float32" datatype.

also factor in that manufacturers may not provide up to date info.
1 HVAC controller I've seen needed a specifc firmware in it to support the json file as they changed their registers info.

getting definitive info for jsons is quite difficult as you've seen , alot of it is trial and error testing with a product.
