FoxESS Community - Owners & Installers Forum

Hi all,
I recently had a FoxESS system installed (H3-5.0-Smart Inverter and EQ4800-L9 batteries) just over a week ago. These are installed to my pre-existing 6.6kW solar panels with a Sungrow SG5KTL-MT_001_001 PV system (using Solar iCloud to monitor).

I'm concerned that I am not enjoying the benefits of the new solar battery system and my bill appears to have gone up more than previously on the first week (as shown on my electricity provider app). Our household average usage is usually average 550-590kWh per month.

My current setting is 'self use' with tariff set as following:
- Peak 1600-2100 Buy 0.42, off-peak 0900-1600 Buy 0.21 and mid-peak Buy 0.32; FIT 0.03 (sell)

I'm also concerned that the Sungrow PV system is not sharing the PV production figures hence not fully utilise the battery efficiently. Interestingly, I noticed the system charging and exporting to grid after sunset at current mode.

Are these normal? Any recommendations to save more buck or utilise the battery more?

Didn't the installers put a CT clamp on that system so the inverter can monitor it?
