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

I don’t think there is any exact battery voltage settings for agm’s with pips. Depends on number of panels, number and size of batteries, temperature and usage. I tend to always set bulk at 58.4, float 54 - 56, LVD 46. That’s using non Australian firmware without kettle komp. If you have utility ava...

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

Good now with fans upside down. Even the big black heat sink is getting hot from the hot air being blown upwards. There is no scc pcb attached to it.

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

I just turned the fans around. Fans are running slow with 350w load and no solar. Even with 1.5kw load, fans were slow. With more than 2kw solar, the fans were fast and temperature was 50. Will see how it goes with fans turned. Would be better if fan speed was controlled by inverter temperature. Tem...

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

After installing lots of MPPSolar inverters for customers, I have a system for myself. 2015 4048ms with late model main pcb and late model scc pcb mounted on top of main pcb but connected to inductors on the black heatsink. New fans in factory orientation. LF1 73 00e 04 12. 12 x 300w panels at 10 de...

PIP-4048MS inverter

Tried connecting a generator to 2 4048 in single phase parallel. 28 PAR. Would not connect in either APL or UPS. Changed 28 to 51G and the one inverter connected to the generator connected on APL. Could only charge at 10A because it was a small generator. I have connected a 3 phase generator to 3 40...

PIP-4048MS inverter

I use CALB CA400's. Trick is to choose very similar Ah rated cells to make up the bank. I am balancing 8 cells now to connect to a 2424mse. The 8 cells range from 430.0Ah to 430.7

PIP-4048MS inverter

Does anyone know what meter is used to measure the Ah capacity of Lifepo4 cells. Mine come with data sheets so it is easy to select similar capacity cells to make up a bank but the meter could help Zenonhost make up his battery bank

The only other thing I can think of is the quality of the generator AC output which might have something to do with the length and size of the cable between the generator and pip

PIP-4048MS inverter

Sounds to me like your problem is with the speed of the generator. As the generator is loaded up, it's speed and frequency are reduced below the low frequency cut off threshold of the pip and the pip then disconnects from the generator. The generator speed then increases to its no load speed and the...

PIP-4048MS inverter

Another consideration with completely off grid systems with no generator backup and Pb is to not have the battery bank too big, otherwise the batteries might not get fully charged often enough to prevent sulphating. I always set LVD to 48v. PV wattage and total daily power use would also influence m...

PIP-4048MS inverter

Yes. If you can spread your single phase loads across each of the 3 phases without ever overloading any phase then you will be ok. The problem I had on the particular job I am referring to had 3 air conditioners which I allocated one to each phase but I could not control what was connected to the GP...

PIP-4048MS inverter

I use a lab power supply to add energy and a 100m roll of cable to remove. It would also be nice to group your 3 cells so that the total Ah capacity was very similar but it would require a lot of effort.

PIP-4048MS inverter

Don't bother with BMS. Connect 3P16S. 16 sets in series, each set is 3 in parallel. Set your low voltage disconnect to 48, float to 54v and bulk to 54.6. Connect a load of about 1kw and bring the battery bank down to 48v checking every now and then to make sure that no group of 3 cells in parallel g...

PIP-4048MS inverter

With 3 4048's in single phase parallel, you have a pool of 12kw to run all your single phase appliances on and will not overload until your demand exceeds 12kw. If you are running a 3 phase appliance, then you have to have the 4048's setup for 3 phase. If you only have single phase appliances and ha...

I think it is water droplets caused by the pressure difference across the fans in a humid environment.

PIP-4048MS inverter

I have gone back to leaving fans in factory orientation. I find that having the fans blow upwards can cause condensation to form on the inside of the inverter.
