Re: PIP-4048MS and PIP-5048MS inverters

I've only recently joined, Welcome to the forum, and thanks for the kind words. However, upon reviewing the factory firmware within the inverters I note that it reports as 74.50. I have not seen mention of any firmware revision beyond 74.40 on this forum. Thus my question: can I safely downgrade fr...

Re: PIP-4048MS and PIP-5048MS inverters

On an MPPT PIP you can go up to the max PV voltage of 145V without problem, if you go 1V above it switches off. I would not say "without problem". From 130V and above, it's been reducing its maximum power to protect itself, and by 145V, its absolute maximum voltage, the power has fallen to zero. Ab...

Re: Actual Firmaware for Steca Solarix PLI 5000-48

Hy, i have a new Steca Solarix PLI 5000-48 bought in January with this Firmware: 72 40 Is it usefull to flash the patched one`s from here. ( 72.20e? / 72.40e?) 😔 Your inverter appears to be a 64V model, so the applicable fully patched firmware is 72.20e, not 7 4 .40e. The behavior of the charging a...

Re: PIP-4048MS and PIP-5048MS inverters

I was celebrating too early. Under full sunlight the PWM charger switched off again and showed 92V on PV input while battery was on 54V. ... Trying with 3S solar string tomorrow. I would not attempt 3S with the PWM solar charge controller! You'll have some 138V, which is well over the rated maximum...

Re: PIP-5048MK inverter

Affer , those panels look to be mounted flat to the roof. That doesn't allow for air flow under them, and they can overheat. Weber had a customer who called him in to investigate an under-performing system. The panels were bolted directly to a corrugated roof, and they overheated. I ended up buying...

Re: Dump loads with MPP Solar

Could it be used to operate a relay (SSR or similar) when the battery is full - switching the PV to the MPPT heater controllers? Not really, unless you never want automatic utility charging. It's designed to start a generator, so it comes on when the battery is weak, and off when no longer weak, or...

Re: Intel on Ioniq 5

In the US, the larger of the two battery sizes goes from 72.6 kWh (international) to 77 .4kWh (USA only I believe, though he says North America). But they get less froot (frunk for them) space.



[ Edit: 77.4 kWh is USA only, not Canada, it seems ]
