Hi, I have a growatt spa3000 hooked up to a Li-Ion battery. I would like to hook up the EPS connection to allow my battery to power my house in the event of a blackout. To do this would I need to do something with contactors to prevent the EPS from being connected directly to the mains or is...

Daft question but what is GINL? Its the only protocol that seems to work properly with my growatt spa3000... Split from hi-jacked thread

Looks like it charges to 3.65v but no more. Is there a setting in the inverter for this? I don't see any voltage settings when running in lithium mode

Hi, I recently acquired a Li-Ion pack with a Seplos BMS. I've got it talking to the SPA via CAN and it seems to be talking ok. The SOC and voltage are all displaying correctly on the SPA. When set to load first the SPA pulls from the battery fine and works as expected. When the time comes for...

I'm pretty sure it won't talk. I'm not sure about the voltages, I can set the lead acid voltages so was thinking I could just tell the controller it's a lead acid?

Hi, Currently my spa3000 is hooked up to a big lead acid bank, I intend to upgrade this to lithium ion this week. I can get a pack that has a BMS but the BMS does not have the ability to communicate to the SPA3000, is this an issue? I've tried setting the SPA to lithium mode but it's constantly...

Thanks for the advice. So on a cloudy day (which is usually is), when I buy my next set should I expect the VOC to be somewhere near the rated value?

Hi, I bought a couple of used panels this weekend, the rated VOC is 38V. Yesterday in full sun they only got to 29V (obviously open circuit, no load). When I put a load on them, the 250W panels peaked at 140W (using mppt grid tie inverter as load). I'm thinking the panels are bad, would you...

What is reactive power? Anything to do with this? Locked to prevent being resurrected (again)

Odd that it's at a low power too, I haven't set that power anywhere..

Now I'm online and growatt have had a look, all settings appear correct but now my battery is charging for some reason again. No idea what's going on. The web interface is crap, very buggy...

Noticed it charging the battery when the voltage was above the minimum which is weird, wondering if it's time related. Hopefully I'll be able to see when it's online

Do growatt have any modern equivalent to the spa3000 out of interest? I don't see anything obvious on their website and I don't think you can get SPAs new.

Thanks for this, I'll wait for the web interface. Do victron do an AC coupled charge controller?

Ah I see, I'll stick with the CT then. Do you think it matters if my CT isn't the one that came with the SPA?

Thank you both for the replies, looks like there are allot more settings here than I can access via the LCD. Hopefully I'll be able to do more when my lan box and RF stick come. One question you may know the answer to, I'm using a non growatt CT clamp, does that matter? I understand CT clamps...

I too am interested if this was resolved. Would using a smart meter be any better at low current than a CT? I also wondered if there is a difference in turn ratio between CTs and how you tell the SPA that ratio? Perhaps it doesn't matter as it just tries to make the reading zero, I have a...

Hi bladerunnerpv, thanks for taking the time to reply. I will also look for the SPH. I've spent quite a few hours trawling various forums but have had no luck. I have ordered the RF bridge so i'm hoping I can get a better view of the settings that way, the LCD display is really hard to work...

Hi, I have just install an SPA3000 and a large lead acid battery bank. I have no solar. I would like the spa to charge the battery during off peak (00:30-04:30) and discharge the rest of the time to offset my load. What I'm finding is that after a day of power the house really nicely the battery...
