The panels going in.
All 8 in their final resting place. Long may they generate.
And the inverter showing the juice coming in. The boss bloke has emailed and he's coming round tomorrow to go through the feed-in tariff paperwork and approve the system for MCS.
The large numbers show the input power being delivered at 517W (just over 1/2 kW). It is a sunny day today, so I assume the system is running at maximum power. This puzzles me as it is a 2kW array. What is happening to the other 1 1/2 kW? Will get back to you on that one... Question for boss bloke tomorrow methinks.
The input voltage of the solar array is steady at 338V (42.25 Volts per panel). I noticed that when it was first powered up and began initialising, the inverter showed the array input voltage at 399V (50V per panel) which is the absolute maximum, as I would expect on a sunny day. Once the inverter had finished initialising, it clicked into 'ready' mode and connected the solar energy to the grid. The input voltage of the array immediately dropped to about 338-340V, and steadied there. It appears that putting the array under load decreases its output voltage.
Not sure what the little graph on the left of the screen is for. I guess it will show the increase and decrease in energy generated over the day.The first row of small numbers below the large numbers is how many kWh generated today (currently 0.2kWh). This will reset every 24 hours (at midnight I assume). The second row of small numbers below is how many kWh generated in total, since installation (currently showing 0kWh - I assume this will update once a day at the end of every day).




Maybe the 517W was what was left over from the 2kW after it had satisfied your current electricity demand?
