Welcome to the SolOptXMR wiki!

TODO

Minimum

• all jsons under the local config directory
• weather: predict 3 days ahead
• proper solar readout
• UIs: console + curses + Qt
• temperature safety
• present multiple solutions in a HTML file
• document rectangle recognition

Major

• measurements
• translate measured voltage into battery charge in Ah
• model voltage loss from attaching consumers
• model charge voltage to State of Charge
• multiply the voltage of the voltage functions by the multiple of (system.json voltage / 12V)
• Support more PCs by improving the combination algorithm (currently up to 2 PCs are supported)
• automatically switching on & off the PCs
• hashrate predictions into model
• OSX support. Issue link

Bugs

• opti app writes to /tmp, rather than to the ConfSol.m_outDir. It might be related to the OSX bug.

Minor

• type hints
• doc: cable sizes vs max current
• doc: fuses on battery, cables (industrial), mppt's radiator, that can overheat and inverter's grounding. Mention synthetic load
• doc: measure and document battery voltage vs. temperature, esp. across the night.
• doc: grounding https://www.solaris-shop.com/blog/grounding-techniques-to-prevent-inverter-damage/

Future work

• compare historical results against each other across time, to measure the discrepancy
• detailed cloud forecast 1 2 3
• synthetically increase the load during days of rapidly alternating clouded/sunny sky to reduce the shock on the inverter
• predict and evaluate future network difficulty fluctuations. Right now we're just displaying the current situation.
• more work on optimization algorithm: fuzzification between the bands
