Three months already!
We have managed to get our system working successfully but with some dodgy fixes to make it work. Here’s some of the points which may be helpful for others trying to emulate our work. @Sn0w3y feel free to ignore this if its causing you overload 
We did not get any response to our invitation for paid help. We are going to be paying someone via upwork to modify the ess balance component with a UI to enable easy changing of target setpoint. This will mean we won’t need to have ess fixpower as well as balance.
We have modified the Sinexcel component to work with the latest Sinexcel PWS2-30P EX. This was no small task for @JimsterCoder because the new protocol is very different to the old! Information here: Real Working System, there are problems with the magnitudes of internal values
@JimsterCoder has done a kludge which brings our battery SOC into the simulator battery component and functions OK.
We have yet to implement any security/credentials checking for user access to UI/backend. This is something we are avoiding because we think it will be difficult…
We have 90% built our first 30kW 2 hour machine (or 30kW/60kWh if you prefer). As can seen there’s plenty of room to scale and we have designed for this.
Hardware consists of
- 5 x Old Leaf Batteries (electrically identical as used in the Leaf but mechanically repackaged)
- 1 x Sinexcel PWS2-30P-EX inverter
- Several computers
- Control/protection systems.
Software is
- Our own TIML custom BMS communicator which talks to Leaf BMS, Sinexcel & OEMS. It also controls the contactors and safety disconnects
- Our own TIML data logging
- OEMS modified to our TIML requirements
We are awaiting approval from the local electrical lines company & electrical inspector signoff then we will be officially running with our prototype. Once its running nicely we’ll be looking for investors to scale the enterprise. Exciting times here
