Hard to understand spend time number watching.
I've got a hybrid system, the Android app seems to time out and be useless so use the web page as its better. My problem has been the installation and the current clamp, make sure it's on a straight cable else it can misread and my iSolarboost ended up in a race situation with the battery discharging into the hot water tank. So watch the numbers and understand your system. What it has done is reduce my energy bills to 8p per day on average.
