Wrenchers,
I am involved in designing an off grid system that will need multiple inverters (probably OutBack). My experience over the years has been limited to no more than 8kW's of inverter on a big system (for me). The load profile is not completed yet, but it is looking like this may require more power if all of the loads were to be on/surge at the same time. The client wants things to run as seamlessly as practical and has the means to pay for a nice system. . Are automatic load management devices worth looking into? I have no experience with them except for one of my off griders (early adopter type) had one put in about 15 years ago on his system and I think it worked OK but it seemed like a lot of money and work to install and it takes up some space. More technical stuff to deal with. . How fool proof is it and is it worth messing with? Vs. adding more inverter wattage? . With OutBack these days what are the Pros and Cons comparing a Radian system vs a Flexware 1000 system? . Why does the Radian line have different ratings per unit of a 48VDC inverter? Isn't the Radian two vented 48V inverters in a big box? . The regular OB VFXR3648's have lower continuous power and surge ratings and lower battery charging amps when compared to a Radian. Two OB VFR3648's @ 7,200VA continuous vs Radian @ 8,000VA; 10.8kVA surge on the 2 VFX's together vs 12kVA on the Radian; also 90ADC vs 115ADC battery charging respectively.
