Output derating of PIP1148MAX

Hi, Slightly bored, I was reading the MAX manual recently. I found this: Built-in anti-dusk kit Could be handy to extend the solar output when the sun is going down. :D Now to the point of the post. Some further reading, I found that the MAX derates once the battery voltage drops below 55V. Here's t...

Cost of running a PIP1148MAX

Hi, I have a PIP1148MAX. Last night was it's first time running the house. This morning I noticed an increase of import from the grid, when there should have been almost zero (PIP5048MG does draw a bit: https://forums.aeva.asn.au/viewtopic.php?p=82594#p82594). Here's a screenshot of imports (1/2 hou...

Re: pip 5048 along with 48v lfp and jk bms -how to set up

Hi, Why do have to change 2024? Premium Feed in Tariff ends in 2024. Might be better off using those panels for charging our batteries. Are you using the changed firmware from here for LFP or the standard? Still have the original FW. I charge to 55.2V & Float at 53.4V. I have another solar charg...

Re: PIP-5048GE/GK/MG/MGX/MAX inverters (with unsafe SCC)

Hi, If you're thinking of automating the lower current switch in series with the pre-charge resistor/bulbs, then this doesn't work. You need to be able to control the main battery disconnect, which means a 250 A 60 V contactor. You could leave the pre-charge resistor/bulb with fuse across that, I su...

HI, Success! Precharge is required for this 11KW MAX inverter. Yes, it's great. Got me thinking ( :shock: ): What happens when we're away and the BMS disconnects? OK if both banks are online, and only one is disconnected. The inverter is still running. If both BMSes disconnect, for whatever reason, ...

Hi "Br", Hi, Thank you for your reply and the settings. Yes the system is connected to grid (or did i misunderstand what you mean by mains)? I was just afraid that the bms would cut off and by this harm the inverter and on top the inverter without battery would be off service as well. So e...

Re: PIP-5048GE/GK/MG/MGX/MAX inverters (with unsafe SCC)

Hi, Dual lamps often have off set pins on the side eg brake lamps Also, dual lamps often have very different power filaments (e.g. 21 W and 5 W), so if you use both filaments in series, one gets most of the voltage and the other barely glows. The one with the most voltage (the lower power half) will...

Re: PIP-5048GE/GK/MG/MGX/MAX inverters (with unsafe SCC)

Hi, I don't understand why the switch would be in parallel with the resistance, that seems to be bypassing them, so it's no different than connecting the battery direct to the inverter. Connecting the battery direct to the inverter is what you want, but only after the capacitor bank has charged. So ...

Re: PIP-5048GE/GK/MG/MGX/MAX inverters (with unsafe SCC)

Hi, One problem with a pre-charge resistor is that you have to parallel it with a switch that can take the entire battery current reliably. If that switch ever failed, the pre-charge resistor sees roughly the whole battery voltage continuously, and will fail dramatically. In my system, I have an EV2...

Re: Old PIP-3048LU won't run from battery

Hi, Anybody have any ideas? Battery is 52.1V. Wild guess: after all these years, the power supply electrolytic capacitors have dried up. It's possibly worth doing a recap to see if it comes good. The vibration/noise sounds bad though, even though it always did some of that. OK. Yeah, the vibration/n...

Old PIP-3048LU won't run from battery

HI, I have this inverter that I bought and installed in Nov. 2012. I replaced it with a PIP-5048MG in Nov. 2016. It was OK when I removed it. The only problem I had during the time it was in service was the LCD screen went blank for a week or more (came good by itself) after a lightning strike, but ...

Re: PIP-5048GE/GK/MG/MGX/MAX inverters (with unsafe SCC)

Hi, Note that shutting down only the MPPT will not help, as it's mainly the inverter's switching of the AC out neutral alternatively to BUS+ and BUS- that causes the current to flow through the leakage to earth. Does that mean that the "08 Error Buster" won't work? I actually bought the LD...

Re: Lifepo4 and Lead Acid a working combination

Hi,

I ran AGMs with my NiFes for a short time. I had to use relays to switch them in/out as my NiFe bank max. voltage was too high for LA (IIRC).

What are the LA doing for your system?

I read somewhere else of this working.

Re: PIP-5048GE/GK/MG/MGX/MAX inverters (with unsafe SCC)

Hi, I am buying a PIP-1148MAX, as an upgrade from my PIP-5048MG (going well - just occasionally undersized). As well, I'm adding a second bank of LFP (ditto). I'm a reasonable amount in front with rebates, and not paying for power since 2012, so figured it was a good time to do this (also we're goin...

Re: PIP 8048 MAX / leakage current from Mains

Hi, I don't have a 8048MAX, but my 5048MG draws current from the grid when in battery/solar mode. Appears to intermittent, but maybe it's fairly constant, and the meter isn't able to read below a certain value. It's only visible when the separate grid-tie solar isn't outputting. https://forums.aeva....

Hi, It's just the way the inverter is designed. In SUB mode, I believe that AC-in, AC-out, and the DC-AC inverter output are all connected together.
