Outback has a plate that is used for the dc brakers it works well for multable SI's and there you put all the fuse protections (class T) or equivilent. I am designing a system with 9 SI's and there we got a cluster box. On Aug 25, 2014 7:44 AM, "Darren Anderson" wrote: > Hi All ­ just wondering w

Why dont you use the m250 anyway as the 250's so far are more reliable then the 215 have been. A little off topic i know. On Aug 25, 2014 1:41 PM, "Jason Szumlanski" wrote: > I had a tough customer recently that grilled me on how we can put a 270W > solar module on a 215W inverter. Fortunately, E

This is something I think about regularly. I guess I don't have a good answer. I will be interested to hear what the more veteran installers have to say. My climate (-50F regularly during the winter) is much different than yours however. To add to the question, how does climate change your

Friends: I have checked out the Midnite purpose-made BOS cabinets for Sunny Island inverters. My problem is they must be co-located with the inverters. The OCPD needs to be closer to the batteries than this usually allows. If your inverters are mounted on an interior wall with the batteri

I had a tough customer recently that grilled me on how we can put a 270W solar module on a 215W inverter. Fortunately, Enphase has a wonderful white paper on the subject. However, it got me thinking... Enphase has demonstrated that higher output panels in many climates (hot SW Florida included) can

Also see all of Midnite Solar products. The SMA epanels are functional but expensive. You may also like their battery combiner. Its good for 1000A DC. Outback FX1000 William Miller Solar > On Aug 25, 2014, at 10:43 AM, Darren Anderson wrote: > > Hi All ­ just wondering what products or general

William, In general I have found the SI to be more reliable than other similar products. My one grievance is the 'tap' error you mention. We have units from more than 5 years ago where this method of failure is the norm in grid-tie battery backup mode. Basically, the power goes out, the SI rela

Friends: It was only recently that I started working on Sunny Island systems. I have inherited two systems from installers that have flaked out and/or could not resolve problems. Both systems are operating unreliably for a number of reasons. Both systems suffered from chronic generator s
