Hi All I see there are a few knowledgeable Goodwe people on here   

 

Im trying to setup my GW6000-es-20 inverter

 

I have export set to 0 

I have set working mode to self-use mode

Back-up mode on

Enable grid charging off

Economic model on

Battery mode 1

05:01-23:59 Discharge 100% power every day and every month

Battery model 2

00:00-05:00 charge 100% power 100% SOC every day and every month

 

I want to  charge up the battery's on cheap rate at night 

and discharge during the day 

 

this seems to work well BUT wont charge from solar 

if I turn of mode 1 

then it will charge from solar but also starts to draw a lot more power from the grid

Help Please

 

 

 

 

Both mode 1 & 2 on grid draw 28 watts

 

Mode 1 off charging from PV but also drawing 130 watts from grid 

Any one able to help ?

Most likely because export is set to 0W and some load is switching on and off at a rate that confuses the algorithm. If you limit export, the reaction time is slow and it causes things like this, unfortunately there is no easy way around it.

OK... this is a different, newer model Goodwe then mine, so take this where it comes from.

I can't help you with the economical mode settings. Firstly because I don't truly understand economical mode on my own, older ES. Secondly because mine doesn't work with the "modes" that you refer to.

I had a problem recently with strange behaviour on my Goodwe. This was resolved with a firmware update. So check the firmware version on your inverter (SolarGo will show you this), record that number, then get whoever is supporting your inverter to upgrade to a newer version (I said to record the current version number in case you want to roll back). This can be done remotely and without needing to restart the inverter.

You don't say where you are and what time of day those screen shots were taken. They don't show a lot of PV coming in, so your batteries are not going to charge quickly. Your battery is not fully charged, but you are getting just 300W from the panels.

You might try this: Just set up a discharge "mode" as you already have. Do not specify times for charging. The inverter should behave as if it's in general mode if there are no time based rules that apply.

Whatever you change, change one thing at a time and then allow time to see if it works. Otherwise you will never know what the problem was and may fall back into the same hole in the future.

If you remove the export limit completely it should resolve the 130w draw you are getting.

 

On the older ES range setting the export limit to zero would cause this, but setting it to a number around 1kW fixes this 130w draw, however on the newer ES range no matter what value you set on the export limit it will still draw have those 130w, you need to completely disable the power export limit (if that's an option for you)

@Neil H which app are using to monitor/setup the goodWe?
