Todo: SRNE inverter protocol v1.7

[HotNoob]

SRNE is fairly common; protocol is modbus. should be a quick addition.

[HotNoob]

implemented in v1.1.2
untested.

[HotNoob]

a lot of weird things in their documentation... such as the signed bits being at the end of the numbers. "sign magnitude numbers"
which makes me wonder if they also have high/low bytes backwards.

so could need a bit of testing to get it going well.

@HotNoob what pdf did you use as base for this one?

sorry title is miss-leading. i implemented v3.9
v1.96 was by @gorbyo #45 #47 #48
isn't a pdf in the repo right now.

i have a v1.7 pdf here though. looks similar to v1.96... but i do see some differences.
SRNE hybrid solar inverter MODBUS protocol V1 7.pdf

i can maybe add v1.7 tonight if you want to give that one a try.

No no, don't worry. Do it in your own time. But when you do, I can test it for sure.

SRNE support confirmed this is the same protocol for my inverter too: SRNE HF2430U60-100 (HF series).

• BTW: Add SRNE protocol 1.96 manual #59

implemented v1.7, fully. untested. i left a few registers in that are unique to 1.96 to serve as a marker for me.

in the v1.1.7 branch.

protocol_version = srne_v1.7

#60 #61 are required to be done at a later date to "complete" the implementation. for a few spots

I have a 240v split phase inverter ASF48100U200-H. Protocol document v1.7 doesn't have Grid Phase B Current register info. v1.96 has it and is working on software 8.03.1.
