[QUOTE="bladerunnerpv, post: 542872, member: 35385"] Hi TimBe, Easy-pv will give you resulting daily profiles of import, export and battery, and behaviour over a year for your specific setup, assuming you enter roof size, orientation and pitch that is. You can easily experiment with the string configurations for you chosen inverter. In addition to the available selection of kit you can enter the panel, inverter and battery specs into easy-pv as custom components if needed. It's possible to enter obstructions on the roof too so the panel fitting jigsaw can be assessed. There are several inverter powers ratings to be aware of, one relates to the max PV input, another to the max battery charging and discharging capability, etc. It's helpful to visualise how a low rated inverter can throttle the input to the battery resulting in export to grid instead. Best savings usually come from maximum self-use of PV power. Battery storage can help get the most out of the PV generation. Easy-pv will not help with assessing the effects of overnight tariffs for charging of batteries, e.g. with Economy7, though, you'll have to get the calculator out for that! Another free option is PVGIS, have a search on the forum, there are some useful posts around regarding both. enjoy! [/QUOTE]
