PIP inverter setting

Post by Roman khan »

Please explain battery equilization,equilization time,equilization time out and what should be their values in setting 30 to 36 for tubular and flooded batteries.

Thanks for posting that, I often wondered what all the other settings were for after 29 because I couldn't seem to find any mention of them in the manual. Luckily they aren't part of the charging regime for lithium batteries so it didn't matter, but at least I know that 30 should be set at Eds so those functions are turned off
As far as setting an equalise charge for flooded cells, I seem to remember 32v for a 24v battery and 64v for a 48v system.
For an equalise to be performed automatically
30 set to EEn
31 set to either 32v or 64v depending on battery pack voltage
33 set to how ever long the battery manufacturer recommends for an equalise charge, but I'd guess 1 hr as a minimum to get all the cells to the same state of charge.
34 is for the time the solar or generator can't get the voltage high enough or hold it for the time set by setting 33. This way the charging cycle isn't stuck in an equalise mode indefinitely. Default is 2 hrs but you can set that for longer if you want, it will time out after the sun goes down or the generator turns off anyway.
35 is to set how often you want to equalise the battery pack, once a mths or every 2 mths etc. Generally a lot of equipment must be turned off during an equalise because the system voltage will be too high, so that needs to be marked on the calendar.
36 is if you want to manually turn the equalise function on and off rather than it occurring automatically. 35 would be set to 0 and 36 used to turn the equalise on, it would turn off automatically at the end of the time set in 33 or 34.

Please some one explain axpert inverter setting no 12 and setting no 13 , how to set these values for different types of batteries and does the values of setting 12 and 13 effects setting 26,27 and 29?

Menu 12 and 13 are only important if you have a grid power back up available. If you are using a generator as the back up supply, you are better of setting menu 01 to UTI so as soon as the generator power is sensed and tested to be stable and suitable, it will use the generator output to power the loads plus charge the battery at what ever rate you set menu 11, this ranges from 2 amps to 60 amps. This charge rate needs to be low enough that when added to the maximum likely load for the house it remains within the generators capabilities. If multiple units are linked in parallel, this setting will be the charging current from each inverter so keep this figure as low as is practical, the default 30 amps would result in a 90 amp charge rate with 3 units in parallel.

None of this effects settings in menu 26, 27 and 29. Menu 28 is used for setting the inverter as a single unit, PAL for parallel units and setting the phase when linked as a 3 phase configuration

If you set menu 29 too high the inverter/s will throw a code 52 when a heavy load is applied, even with lithium batteries. We set Menu 29 to 46v for a 48v pack but we also have a low cell voltage alarm set at 2.8v and cut at 2.6v to allow a bit of voltage sag if a very heavy load is applied for a short period, like an induction motor start up.
We also use 58v for menu 26 (bulk charge)and 54vdc for menu 27(float charge. The reason we set them a bit higher is because the PIP inverters do not have separate voltage sensing wires but rather sense the voltage at the main battery cable connections causing the inverter to read a higher voltage than the actual battery terminal voltage. We also have a high cell voltage charge cut so we don't really rely on the cells being perfectly balanced. Cell balancers work effectively if a cell voltage is higher than the other cells, so combined with a high cell voltage timed charge cut allows the balance to do a better top balance.
