Took the plunge, have the 5kw inverter and the 5kwah battery from Sunsynk. Not sure what settings to use to prioritise solar during the day, eskom at night and battery when there is load shedding. Any advice would be appreciated, thanks.

It sounds like previously you had an inverter where you set priorities. Things work differently on a Sunsynk. The first question to ask is whether you want to sell/export energy?

Nope, not selling or exporting.

Ok. Next, have you installed the CT at the main breaker and are you willing to play with the battery level?

Welcome here. You can read under the inverter section and find many configurations where other members asked how to do the settings. Numerous examples of the different screens as a guidance. 

I would be willing to play around with battery settings but no CT installed

The CT is essential as per the manual to prevent sending back into the grid. 

The CT is also important for feeding energy in to your non-essential loads (geyser, pool, etc.). After that you can enable the timer under system mode to let the battery run down at night and charge with solar during the day.

See attached with a few questions, thanks. 

On the inverter you have the option to select grid charging or not with these time slots. Solar will always be maximized but with limited essential loads and no exporting to non essentials, you can only charge the battery to 100%. Typically you want to allow for grid charging to 100% in the afternoon, keep it at 100% until 22:00. Then allow it to run down to 50% at 05:00. These setpoints will vary depending on your loads, PV size and battery size. How much PV do you have and what is your base load?

I have 4500watts installed (8x 550w panels) base load is low (only 2 people in household) so around 450w to 500w my electricity is paid for me, hence wanting to use solar during day, then eskom, then only battery (during load shedding).

And I guess that Energy Pattern should remain on Priority Batt not Priory Load?Thanks

If I made all time slots 100% for SOC would they me that battery would only run if eskom was off (load shedding)?

Yes, but that is the same as not using the timer at all.

Which is OK with me as I only want to use battery during load shedding, as my electricity is paid for, so just need the battery when power is off (load shedding)?

Apologies for the naive questioning, I really know very little, only installed the system yesterday,  and then saw the battery being used this eve, even though there is eskom power. Thanks
