Hi there,
Its been a long time ! I still procrasting, with rotors build for my piggon 10footer in garage, with all metal work painted, AWG14 waiting, with no good wood for blade found in two years.
One year ago, the compagnie i work for moved toward regular solar controler to OutBack MPPT and VFX inverter/charger. We provide service and support for VHF and PTP in remote regions of Quebec for wood harvesting. Shelters are all build on mountain top, with old 12v kit remplaced by 24v (for proof of claims from outback, and verifing RF interference produced to VHF spectrum) and now 48V system. Our most power hungry equipement accept 110V or 48V.
Folloing PV arrays already in place, we put all array in bank of 5 serial PV on one or two FX in case our PV are or different types. We use PV combiner outdoor since sometime there are many array. It was a big deal to have evrething checked and re-wired, blown pv removed, benefit of higher voltage in wire runs.... The gain in efficiency of the overall system seem good, the generator run less hours (% hard to calculate in only one year)
We enjoyed watching the control pannel showing 56 amps rushing at 54v when we started our lastest site. We have a 48V bank of 2000 Ah
This summer, we had a curious problem, that we asked to our dealer, and then outback support. The only answer we had is «Its impossible it shutdown itself» but it did.
The only 110V appliance we run is verry small, 1Amp in status screen. We had 3 issue of AC inverter shutting down, two when we were at the shop, and one when we were on the site. We never had such problem with 24V unit, and it occur only on 48V system. Sensitivity Srch was set on 0 (suppose to mean always ON?) and 1 on the other unit
This function is intended to cut inverter down in case it run unloaded if i remember well.
We put a regular 48/110V inverter with a relay sensing VFX output, and if output turn off, the other inverter automaticaly run without interrupting our communications. Im affraid of the day the relay will die, and the two inverter will fight each others.
If something similar happened to some of you, i can get the book in hand to give more details and exact menu words. It would be nice to understand why inverter went in dumb mode.
We use midnight solar pre-wired pannel with a VFX3648, a FX80, FlexNet DC Hub and Mate. Our 3 48v system had some difference in wiring, on FlexNet shunt wiring and FX input in different side of input and battery breaker. We are happy even tought of product.
cheers
