Hi,
I have an export enabled ESS system but due to our location, our export-power is capped 50% below my PV generating capability. By default, the Colour Control GX ESS software priorities surplus PV to battery charging so by midday the batteries often full, with little or no energy being exported. Then, from midday, when generally higher PV output is available, the PV is often throttled due to the export cap and full batteries.
Is there a way to delay or limit PV battery charging until midday, so all PV power can be exported in the morning, regardless of battery SOC? From midday, when there's more PV energy than I can export, I’d like to charge the batteries too, thereby making maximum use of the available energy.
I know this is probably an unusual problem but I’m grateful for any ideas.
Thanks
Paul.
