[QUOTE="binky, post: 460804, member: 490"] Ok HF inverter is pretty old school, and will require a higher wattage to start up, but that picture shows the bar graph of output. On the day that was taken you have clearly been generating. From data sheet it would seem you have a single string inverter, so it should be showing panel voltages on the display along with grid voltage on RHS. The fact that it isn't may just be a software glitch or display fault. There is absolutely no need to access the roof to check panel outputs, or check for earth leakage - try a different company. As Andy has pointed out, it is possible to check the Voc and Isc values with simple test gear. Clearly checking on a sunny day will make any results more obvious. The only thing that would require roof access is finding an earth leakage fault, after confirming at the inverter that one exists. However, as no fault codes are being shown, it would suggest the inverter and system is working fine. There is one exception to that, I have had Sunny Boys fail to convert DC to AC power, but display no faults. This will be obvious, if the sun is out and there is little useable power being generated, you can also keep an eye on the generation meter, if it isn't changing the system isn't outputting [/QUOTE]
