Just what I was looking for. Thank you @Kosie. Just curious though, you connected battery 1's B connector to battery 2's A connector. How come not A to A or B to B? You are right, the manual is very messy. One last Q... is your inverter comms cable a standard network cable or a cross over? Thanks

Thanks @Buyeye, let me see what that does.

Neat @Buyeye. I want to achieve something like that too but at the same time, I don't want my battery to be dead at sunset which is the conundrum. This is why I thought that a setting which allows a switchover to eskom at around 6pm would be great.

Hi all, New to the forum so please go easy . I'll try to be detailed enough and hopefully this thread assists many others with the same intention. Setup: 2 x Growatt 5KW inverters (5000TL), 1 x Shoto 4.8 Kwh lithium battery (SDA10-48100), 12 x 330W Prime Solar panels. Home power setup and usage: No geysers / ovens connected to the inverter system. General average power usage on the inverters during the day at any given time is under 1000W (probably 500w average), except for when the microwave/toaster/iron/aircon is being utilised. What do I want to achieve? - using as little as possible of Eskom power. The problem? - When the sun starts setting, it depletes the battery until there is no more sunlight and then a large amount of Eskom power is required to recharge the battery. The setup seems to be singing along nicely however I would like to tune it to be more efficient in terms of battery charge/discharge. The main aim of making the system more efficient is that when the sun starts setting, the battery starts draining. At a point where there is no sun available (i.e. PV power production = 0W), the inverter switches to utility power (Eskom) which uses a considerable amount of utility power to replenish the battery back to 100%. This of course reduces my net gain from the day's solar power production 😕 Is anyone able to assist \ have experience with making the system more efficient? I've potentially found the settings "hidden" within the wifi data logger module's web interface (accessible via the mobile app too) which will potentially solve the issue but I'm afraid to make the change! 😂 See green highlighted section below. (I haven't received much assistance from Growatt hence turning to this forum for assistance). I would like to avoid charging the battery using Eskom, which would require me to switch over to utility at approximately 6pm at the moment (Cape Town) and ideally at that point, I don't want the battery to charge anymore (especially from Eskom). Once the sun starts to rise (after 5am currently), I would like it to switch over to PV power. Any advice on how to achieve this and would I need to configure both inverters via their respective wifi data loggers?
