PIP-5048GK standby usage
#11
All switches can be automated with proper hardware around it.

I think you can find parts of it here: http://forums.aeva.asn.au/viewtopic.php?t=4332
Though i guess some changes have been done towards the GK model.

I dont own any PIP any more and was some years i did play around with it as well. I dont evem remember how to turn of the inverter leaving mppt running? Big Grin

With automation if you solve above i can help. You can for instance easily do it with Node Red and a raspberry pi to controll it all

Yes i guess you can always make mechanical switches automated by using some automated mechanical servo or something like that. I don't own a PIP either but i am in the process of deciding to get Victron or the MPP 5048 MK. I know alot about automation, it's just what's possible. I will open a separate thread about Victron Wink

Go victron i useage is an issue. You also get better support and warranty

Very strange that you don't see anything in PIP Software. Is that usual to it?

Hi, sorry for being super-late in replying!
I have the Canadian Solar CS6K-280P panels, 12 of them. Vmmp is 31,3 V per panel so times 12 gives 375,6 V which suits the "high PV Volt" input of the PIP 5048-GK.
At 120 V (which is the charger start-up voltage) it shows no Amps or Watts coming from the solar panels, but it does reduce the power flowing from the batteries to the inverter.
When it actually starts converting a decent amount of power it is shown in the watchpower screen, so no issue there.

I'll look into switching out the MPP solar for a Victron inverter in the coming months or I might put the powerwall setup "on hold" for now (based on some local incentives for solar installations changing from 2021 onwards).  Huh
We'll see what the future brings.

You just have to weigh in the entire month's average. If all you have is extremely cloudy days, then turn it off. During winters I still net overall a positive so I leave it on.

If you're willing to do extra work to maximize your output, then if you have a manual transfer switch, shift the load to your grid. Then turn off the inverter portion of the PIP and leave the solar charger on. That way your idle drops down to around 15W, which then leaves your battery charging via solar until it reaches 100%. Then turn the inverter back on and flip to battery until it is depleted and repeat the process.
Hey not2bme, how did you achieve to put the inverter portion of the PIP off?

After testing some stuff out myself, it seems that shutting down the inverter with the On/off button on the display panel puts it into 'standby mode'.
This does allow solar to charge the batteries but provides no AC output. Exactly what I was looking for. I've installed a (manual) transfer switch in my main switchboard to get the loads back on grid power if needed. Since it's been pretty miserable weather for weeks now, that comes in handy!

Wim, that's why I choose for a separate charger. Use the PCM60X to charge the batteries. If there's not much sun I switch off the inverter, the ATS switches to grid.
We live in same country so I know how low the input during these winter months is. Now production is ramping up. DEC & JAN I used 30kwh, FEB 80Kwh.
Last week I added an extra 8 kwh and already used 20kwh this month and we're only 4th of March.

P.S. the standby function didn't worked for me. I have some small loads of few watts for powermeter and that tripped the inverter to leave the STBY function. Glad it worked out for you.

Franky,

I simply powered the inverter part off with the button on the front panel. I was pleasantly surprised that the charger part still worked in this use case.

All these changes make the process quite complex, yet still leave some issues unanswered. I'll be switching my setup to a regular grid-tied solar setup (for now).
