Easysolar II GX not charging from a/c coupled PV. How can stop it exporting to the grid and make it go to the charger. Setup is ESS optimised with battery life using Pylontech US2000 and a current transformer on the incoming grid.
asked
Should a/c coupled charge a battery in ESS mode?
I don't see your AC PV on the ccgx screen. How is it being monitored or was programmed into the system?
The A/C coupled PV is connected to the AC 1 output and displays in the AC loads. The grid power is measured by a current transformer (CTR110000500 ).
Try limiting grid feedback or maybe prevent grid feed in for a bit until you are happy with battery SOC. See if it will charge up from the ac pv
Turned of ac coupled feedback excess but it had no affect in passthru. It only comes out of passthrough when the batteries are fully charged. It is in ESS optimised mode and not batterysave.
Hi @Gat
the system is in passthru, please read the manual about that:
(see Q4)
https://www.victronenergy.com/live/ess:design-installation-manual#faq
Yes, I have looked at Q4 and none of them apply. Any other sugestions?
Q4
1. Grid meter not enabled.
2. Battery information is displayed.
3/4.CCL=50, DCL=50 SOC quite high, Ac current limit not exceeded.
5. UK grid code, No aux.
6. Grid to inverter <2m.
Have now tested with AUX and LOM disabled. No change. I have now reset them back to default settings.
If the passthru caused by one o the items in Q4 would it still be able to go into the abosrption mode and pass dc coupled pv to the grid? when my Easysolar II gets to about 98/99% soc it comes out of passthru and into absorption/discharge/bulk mode. It then allows a flow through the inverter.
Then a few minutes later.
