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

It is listed as 145V if I am not mistaken. Yes, that's an ordinary Axpert MKS PF0.8. Just like my PIP-4048MS. So that means if I have a spike in my consumption that exceeds my available PV (e.g., coffee machine or vacuum cleaner), it would then not only stop charging the battery but if required eve...

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

I am a new member from South Africa :) Welcome! I have an older 5kVA / 4kW model ... Ah but what model? See next question. I have read in other places on the web that my inverter is not able to mix PV and grid sources. Is that correct? It depends if it's a 450 V max SCC model or not (i.e. it's an e...

Re: Prelude conversion project - some questions

Personally, I don't like to see permanent traction battery voltage in an unattended vehicle. I would prefer to see ELV segmentation, which I think of as <120 VDC, except when the car is on, and with a special exception for periodically re-charging the auxiliary battery when needed. Even then, there ...

Re: Prelude conversion project - some questions

if so, a cap and a double pole relay could be built cheaply and reliably to create 24v for turn on, then 12v for running. Surely there is an arrangement with some diodes and a capacitor that could eliminate the relay. You do need a push-pull inverter capable of coil current however, and your drive ...

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

Why is it so complicated to set the limits other values? One of the reasons is that the settings are packed into CAN packets and sent from one machine to another, when they are paralleled and/or in three-phase. You have to keep track of the new bit pattern meanings, and make sure that all the uses ...

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

A very typical batterie nominal voltage is 44,4V. Upper limit 50,2V, Lower Limit 38,4V It would be great to change the PIP-5048MS to this values to bring a hugh mass of batteries into second use applications. Do you think this is possible? It would be possible, but I think you would not be able to ...

Other lithium ion batteries have cobalt or NMC or other cathode materials. Hence my confusion over what you are u...

It's home made Lithium Ion. That doesn't...
