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...

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

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.

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.

PIP-4048MS inverter

Old type with black heat sink on top. Airflow direction up. You would not think this setup would make much difference because the fans are at the bottom and the heat sink is at the top but if you try it you will see that the heat sink is cooler. Also depends on the firmware revision because some hav...

There is a socket marked CN12 (FAN3) at the top of the main PCB in the middle. Having the 2 main fans mounted upside down keeps the scc heat sink a bit cooler. Having the solar panel array working voltage closer to 60 keeps the scc heat sink temperature lower but solar charging using a higher string...

Has anyone tried the hybrid mpi models. I see 3k, 5.5k and 10k have AS4777. I assume 5k is not included because of 900v max pv input voltage but 10k model is also 900v

Old type scc can be connected to new type main pcb. New type scc can be connected to new type main pcb if the spade connectors of one inductor are removed and joined to 2 longer wires. New type scc cannot be easily connected to old type main pcb.
