[QUOTE="wc1966, post: 548702, member: 36980"] I recently installed 8kw of solar on a south facing roof with a 5kw Hybrid Givenergy inverter and a 9.5kw/h Givenergy battery. An oversized system!! I'm on the flux tariff and as most flux users one of the core strategies is to dump the battery as much as possible between 4 and 7pm. I've I have set on about 2kw discharge so after 3 hours i tend to retain about 25% to get me through the evening. The question should I try and charge the solar battery during the day or instead just fully charge 2-5am then discharge and good for max export. On poor days like yesterday things come unstuck and at 4pm I only had 60% on the battery so export is limited. I other consideration is should I have a different strategy in really decent spells of weather. Take the example below when I have clear skies. Am I better delaying my charge till the sun gets high, then using the excess >3.6kw to charge the battery or have I understood that incorrectly? Any advice welcome, I'm on a rapid learning curve with this stuff!! [/QUOTE]
