It is an android unit and I rotated on paint as you did but it still comes out upside down
I even turned the tablet upside down and tried again!

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

For heating water there are 48v elements available to replace the ones in hot water tanks a dual element tank would be ideal one for the grid (top one) the other dc solar (bottom one) Here is a view of the wireless meter now operating on my system and its 40 meters through various walls Note I fitte...

If you happen to have an LFP battery and a coulomb-counting type SoC meter (not the crappy voltage-based one in the PIP/Axpert),
Just installed this one its working well

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

Have you consider water cooling? :D I have no problem with overheating because I have 3 PIPs (12kVA total) and only 5.3kVA PV installed so they do not work in full power mode. :) I have two PIPs in parallel so 8kVa and only get to 50% load I designed the system to run at no more than 50% normally 2...

A story about fans> I have changed all mine so they push air up I have also added two more 120mm fans to the top vents on the inverter drawing air out. I have used a 12v version of this temperature controller to operate them you could use a 240v version and my friend has aswell https://www.ebay.com....

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

The reason for the relay on the output to put an earth on the neutral when inverter is on is because you should have only one earth/neutral link if there is a permanent one on the output of the inverter in bypass mode you will end up with two The neutral coming in is disconnected in inverter mode so...

Hello CrOhN Is there an earth on the neutral at the output of the inverter if not it will go to about 90 volts and can case it to trip the mains differential.

Re: AGM battery problems

There are a number of manufactures of the systems so searching around may find them at a reasonable price
considering how long they should last it will not cost much in the long run.
The only thing is when you have to change the electrolyte in the NiFe cells thats going to be messy!

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

Hello erland82 You could turn the inverter on/off with switch when you get there but the MPPT stops as well Best would be to keep your 4860 MPPT working. For heating before you get there why not use a 48V heater it can easily made A length of zinc coated steel wire wound into a long spring like coil...

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

"that respectively force an inverter into standby mode"
Can units in parallel be shut down say one of a pair.
What happens with paralleled units if the load goes up will the standbys come back on?

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)

I think you may have misunderstood it was not a 240V ups I had, for over 15 years a 48v DC system
and I still have it running 48v to 12v for various gear and some that runs straight off 48v.

I have my ones two homes , four inverters mounted on ply wood I do not see a big risk of fire
They could be mounted with fiber cement board behind them which has a good fire rating
If mounted on a metal surface earthing and insulation need to be considered

My inverters read the AC voltages 3 volts higher than actual as its all of them (6) has anybody checked to see if they have the same
and can this be changed to be accurate?

Re: PIP-4048MS inverter

Re: PIP-4048MS inverter

Yes with two you get double everything so you could charge at 120amps.
Note both units charge amps are set interdependently solar and grid/generator.
Yes the price of the other brands is eye watering even after buying spare inverters (which is what I did) you still have change.

Re: PIP-4048MS inverter

Replacing a failed 4048 in a parallel set is a problem people will increasingly be facing. I do not have a solution. My solution was to have a spare infact I have two, one for each location. When you consider the difference in cost compared to say a victron unit a full set of spares is still cheaper!

Re: PIP-4048MS inverter

I would look into warranty return before opening.
Note I had more panels on one unit at one point but it maxed out at 61amps even though more power was available so it should not have overloaded.
