Hi Everyone, hope you can help me out.
I have a Givenergy EV charger and a Givenergy Hybrid 5kw Gen 3 inverter. I routinely charge my EV via an overnight schedule, and this works just fine.
On occasion though, when its sunny I might want to put a few more miles on the car with an “ad-hoc” charge during the day. The problem I face is that doign this seems to mess up the settings for the overnight charge.
Currently, when I want to do an ad-hoc solar charge, I will go into settings and set “enable solar charging” to ON, and then just plug in.
When I finish the charge, I then have to make sure to remember to turn off plug and charge and also remember to turn back on “charge at max power”.
If I dont do this, then my scheduled charge wont work properly (Charge either fails or is very slow).
All of this seems rather fiddly. Is there a better way to achieve what I`m after?

Hi.
I do exactly what you are wanting.
Basically, enable ‘solar charging’ , priority to EV, prevent battery discharging to EV, charge at Max current.
When the EV is plugged in and solar generation is over 1.4Kw (roughly) it will send the excess to the EV and dynamically alter the charge current as required depending on solar generation.
Your set schedule will still happen each night as normal.

Good to know, but what I was asking, was, do I need to change settings each and every time I wish to perform an ad hoc solar only charge?
I would like to avoid changing settings just to do this.

If you put the settings in mentioned then you do nothing at all except plug the car in.
Do not enable plug and charge as the GW will simply charge the car if generation is over 1.4Kw and dynamically adjust charge current as required. When the overnight schedule
Kicks in it charges at full rate (7.4kW) for the period set.
You do not need to keep turning ‘solar charging’ off and on. Just leave it on.
You will notice that charge current varies depending on panel output (I’ve seen 800w to 7Kw going to the EV depending on weather).
As long as you have set the overnight schedule to charge at 32A (max) that’s what it will do for that period.
Make sense?

Why should you want to charge from Solar? We export at 16.5 pence and Charge ar 6.7 pence. It don’t make sense to loose money.

Of course its not financially advantagous to charge over solar, but if you need a few more miles on the car and its sunny, its the path of least resistance. Its an exception scenareo.
I have an automation in HomeAssistant that looks at the current import price, soc of the battery and then if the price is low and the soc is high sends excess power to the car, trickle charging on the very sunny days where agile export prices have dropped to nearly 0
