Storage minimises electricity purchased
Brief set-up guide was clear. More leads supplied than needed. It would have helped to know the COM data rate was 9,600 baud. The provision of back-up in a power-cut was an unexpected bonus, so this is used for lighting circuit. The spec in the manual states the switching time is <10mS. This applies when mains power is restored but at the start of a power cut it takes 150mS before back-up starts. Switching is the only occasion when the inverter makes any noise. Running at 3kW the air rising off the unit is 7 degrees Celsius warmer than the incoming air. If mounted a cupboard recommend inflow and outflow vents of 100 cm2. Display was initially confusing: Grid power means what is coming into or leaving the inverter not what is flowing from the national grid into the house. This can be found under meter information. By using a 1kW kettle and using microwave or toaster only one at a time the consumer is importing an average of 0.146 kWh per day and using 6.13 kWh of that generated by solar panels and using 1.34 kWh of gas.

Initial impression looks good.
It is taking some time to install the equipment myself. No issues have arisen that could not be resolved without a little research. Most items installed but power not connected yet.

Very straightforward
My first foray into domestic battery storage. I started by mounting the unit on a wall, which is ideally a two man job. It is then a bit of a contortion job to wire the unit up unless it is well above head height. I recommend wiring up the unit while it is flat on a bench and then fix it to the wall. Commissioning was straightforward and the system was quickly up and running. Bear in mind that the front panel display is text only and does not have a color system mimic like some of the 4G series.
