[RE-wrenches] Real world production data for bifacials?

2020-03-22 Thread greg egan
Wrenches, good health to you and your loved ones.  I have a client that thinks he wants bifacial modules since his site is in the Alaskan arctic and they have snow a significant amount of the year.  I've been installing standard modules on racks that can be set at 90 deg in the fall and set

Jay, Do you mean: use the Aux relay to activate the Remote Power Off? What is the low battery setting range for the Aux relay? I don't see it in the manual. Kent Osterberg Blue Mountain Solar On 3/22/2020 4:04 PM, Jay wrote: Ray, Have you heard bought about using the Aux relay to control

That's the whole point: we need the LBCO to be higher than 48v to catch the beginning of that steep drop off, so that there is still enough reserve left to keep the monitoring and solar charge controllers in operation, and avoid the dreaded dark start.  With Simpliphi, we don't have the dark

Wrenches Don't let the LBCU scare you as this battery has such a flat SOC line that when it falls off there is not much left in the tank. In addition set the flex net to low SOC at 15% and critical to 10%. On Sun, Mar 22, 2020, 12:15 PM Sindelar Solar wrote: > Specifically with Blue Ion, the

The possibility of dark start and 30% higher cost are 2 reasons we have preferred Simpliphi lately. Simpliphi just requires resetting its breaker on top of the battery.  Also the Simpliphi allows more layouts, so it doesn't stick out into the room.  We have one customer that has a system with

Specifically with Blue Ion, the installation manual recommends 48V as LBCO, but also recommends setting it a bit higher: "Recommended Low Voltage Disconnect Setting: 48 VDC (~2-10% State of Charge) BMU will power down the Blue Ion 2.0 cabinet at 44 VDC (<1% State of Charge) Based on system

Wrenches Blue ion is a better solution, no extra parts cables or racking, all part of the "system" and works very well Jerry On Sun, Mar 22, 2020, 11:44 AM Ray wrote: > Blue Ion, and Simpliphi that I know of. > > Ray Walters > Remote Solar > 303 505-8760 > > On 3/21/20 2:48 PM, Dave Angelini

Yes Sonoma county requires 30' minimum from ground arrays for fire setbacks.  and by extension 30' from property lines (as an array owner can't control a neighbors brush removal) More is surely advised!  I imagine other CA counties have similar requirements. Dave Angelini Offgrid Solar wrote

Yea weird times. Ha I guess Zeke figured it out, oh well I’ve got 4 meters, and they agree if and only if they get to full every few days. If it goes longer they get further off. And I’m talking multiple trimetrics all set exactly the same. Given the flat curve of LipO, I don’t know if I
