I have a EO mini Pro and will never ever buy anything from EO again. I'm a Electrical contractor and off grid solar installer and install complex systems daily. But this little piece of garbage beat me. First 3 to 5 hours of training noone tell you about, second it can never work anyway till you get the stock 'assigned' to you after a call to tech support - and im in australia so this is 7pm at night. I guess this is how they ensure you are trained. Several calls to tech support, about 12 hours total over 6 months to get it working. If the job was for a customer I'd be going bankrupt. Instead of making thier garbage better they just make the training longer. It's anual renewable too so you have to do it again. I installed a $1.2mill battery by ABB/Samsung in the same timeframe without annually updated installer training... It's very "home made" with hobby grade electronics. Raspberry Pi as the processor. The plastic isn't uv stable, used to be black, it's now white. I'd be surprised it's still there a year from now. It's solar mode uses solar produced. This is useless as my house also need that power. If it used solar that was being exported it would be excess solar power and be essentially free power. They way they do it is solar power(that's not excess) goes to the car and then the house imports coal power at the same time. Unlikely to save you any money at all Just chuck their instructions in the bin, and move the CT to the incoming mains and it will now put power in the car that was going to be exported. Excess or spill solar will now charge your car for free. Tech support is useless. Very expensive. The app is crappy and no API or any other input. Don't waste your time and money on this company.
