# SolarMax Binding
This binding supports SolarMax PV inverters.
# Supported Things
This binding only has a single inverter thing that can be added manually.
The SolarMax MT Series is supported (tested with 8MT2 devices).
# Discovery
Auto-discovery is currently not available.
# Thing Configuration
Each inverter requires the following configuration parameters:
| parameter | required | default | description |
|---|---|---|---|
| host | yes | hostname or IP address of the inverter | |
| portNumber | no | 12345 | Port number to connect to. This should be 12345 for most inverters |
| deviceAddress | no | 1 | Device address for devices connected serially. |
| refreshInterval | no | 15 | Interval (in seconds) to refresh the channel values. |

# SolarMax Commands
During the implementation the SolarMax device was sent all possible 3 character commands and a number of 4 character commands, to see what it responded to. The most interesting, identifiable and useful commands were implemented as channels above.
Here is a list of other commands, which are known to return some kind of value: ADR (Device Address), AMM, CID, CPG, CPL, CP1, CP2, CP3, CP4, CP5, CYC, DIN, DMO, ETH, FH2, FQR, FWV, IAA, IED, IEE, IEM, ILM, IP4, ISL, ITS, KFS, KHS, KTS, LAN (Language), MAC (MAC Address), PAE, PAM, PDA, PDC, PFA, PIN (Power Installed), PLR, PPC, PRL (AC Power Percent, PSF, PSR, PSS, QAC, QMO, QUC, RA1, RA2, RB1, RB2, REL, RH1, RH2, RPR, RSD, SAC, SAL, SAM, SCH, SNM (IP Broadcast Address??), SPS, SRD, SRS, SYS (Operating State), TCP (probably port number - 12345), TI1, TL1, TL3, TND, TNH, TNL, TP1, TP2, TP3, TV0, TV1, TYP (Type?), UA2, UB2, UGD, UI1, UI2, UI3, ULH, ULL, UMX, UM1, UM2, UM3, UPD, UZK, VCM
