Hi:
I hope post finds everyone well. I have a question about ending amps for absorption time.
System parameters below:
Here is my question. I have my absorption time set based on a specification from Surrette (T=.42 x (428aH/42A) = 4.2. I recently extended it a bit to get the SPG up. Will the the ME ARC 50 support having two Absorption ending parameters or will it only function based on one. I have it set as time but I would like to put in an end amp setting as well. I don't know if it supports having an absorption time and an end amp setting.
Does any one know if it will look at ending amps if it has yet to reach the absorption timer?
MS PAE Magnum 4448 Inverter
-ME ARC 50 Controller
-Magnum E Panel
-Magnum BMK
-Magnum Mag Web N
- 2 Classic 150 charge controllers incase one fails
-12 x 260 watt solar panels. 6 on each controller.
-8 x S550 batteries in Series
- Cummins Propane Generator
-Magnum Auto Start N
Current Setting:
- Absorb 60.0v
- Float 54.0v
- Absorb time calculated using
-T= .42 x 428 /42 = 4.2 hrs
-Therefore: absorb time 4.2hrs
- Charging amps at 10% of C20 = 42 amps
- Inverter is 60amps DC output. Currently set at 70% max charge rate (70% of 60amps is 42amps) with a max charge current set at 40. The options go in groups of 10 so the next option was 50 which is over 10% of the C20 rate.
- We currently do not have a lot of sun and so the generator is set to take the batteries to float.
- AGS parmeters:
- Start voltage is at 46.8
- Stop voltage is at Float
- BMK parmeters:
- Bank efficiency is at 80%
- Amp hour rating of batteries is 420aH. --BMK manual states to set it below the actual bank size. Goes in increments of 10.
-Generator:
- Magnum stats to set the AC in amps as what is available on only 1 lag of the generator. In this case it's a double pole 30 amp breaker which means the AC in amps would be set to 30 for 1 lag and 30 on the other.
Classic 150 Settings:
- Absorb 60.0v
- Float 54.0v
- Absorb Time 4.2hrs
- Classic 150s are linked in follow me.so they share charging phases at the same time.
- Also sharing ground fault and battery temperature sensor so that they compensate as one.
