+# 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                               |
+| port            | no       | 12345   | Port number to connect to. This should be `12345` for most inverters |
+| refreshInterval | no       | 15      | Interval (in seconds) to refresh the channel values.                 |
+
+
+## Properties
+
+| property        | description                                            |
+| --------------- | ------------------------------------------------------ |
+| softwareVersion | Software Version installed on the SolarMax device      |
+| buildNumber     | Firmware Build Number installed on the SolarMax device |
+

+
+### 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 (DeviceAddress / Device Number - only used if the devices are linked serially), 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
+
+Valid commands which returned a null/empty value during testing: FFK, FRT, GCP, ITN, PLD, PLE, PLF, PLS, PPO, TV2, VLE, VLI, VLO
