Thank you for the great forum, Safe Driving over the weekend. Sincerely Jason

Hi, I am new to solar power. I have recently installed a system with:

 

1 x 5 kW 48 V Kodak King inverter

2 x Pylontech US 2000 batteries

2 kW array of panels

 

Output source priority is set to SBU.

 

At the moment the system appears to configured so that the batteries are being charged from both solar and the utility. 

 

I want to change this, so that only solar is able to charge the batteries.  It seems I do not have enough storage on the system and the batteries run out during the early hours of the morning, at which point they charge from mains.  This seems pointless.  Mains should take over and provide power to my home when the batteries are low and there is no/insufficient power, but mains should not be charging the batteries.  At least not normally - I am happy to occasionally manually change this for example if load shedding is expected and the batteries are low due to say cloudy weather.

 

Ideally - what I want is guidance on the best settings to optimize electricity saving and maximise the use of solar while minimizing the use of mains power.

 

Thanks.

Setting 16: I assume you have the default option of SbL UCb (solar energy for battery first, allow utility to charge battery). If so change to SbL UdC (disallow utility charging).

There is also a SLb UdC option (solar energy for load first, disable utility charging).

This is all in the user manual.

Hi Tursiops

How was the Kodak and Pylontech compatability?   Was it as simple as connecting them directly, or did you need another device (like ICC)?

It is plug & play. The Kodak King comes standard with Pylontech port & cable. Really simple

Thanks, reading the manual does help, I glossed over it and got stuck at trying to fathom out what is meant by Eco mode.  Question for another day.  However, I still have a problem - I set it to SLb, UdC, but it seems that solar is still only charging the battery with the load being supplied directly from the utility via bypass.  I would have thought that on this setting, only spare capacity from solar would be directed to the batteries?

I agree with you.

What is your setting 10 (Operation Logic)? That's unique to the Kings.
