Louis; I have seen that pilot light save off-grid on-demand water heaters
from freezing many times!
Often old technology has advantages that don't make it into new, high-tech
equipment press releases.
Since I work so far off grid and only with small systems, the newer water
heaters needing
HI All,
I talked to Morningstar today and here is how the tristar work.
To get to the absorb time of 120-150 minutes in CC mode ( + an additional 30 or
more if the batteries got below 12.3v nominal the day before)
the controller must get to 15% duty cycle. So for the 60 amp its 9 amps. When
CA Wrenches,
My installs are mostly in unincorporated towns and properties outside
of small towns in the Sierras. I understand the requirements for walk space
around PV arrays here in CA on residential dwellings. Do these requirements
pertain to "outbuildings" such as shops,
I have a customer who has 6 siemens 48w panels that are 20 years old (hooked in
parallel to a 12v battery). He says that 4 of them have failed in that there is
no output unless he bypasses the diodes. However he pulled the diodes and
checked them on a diode check and separately on a battery
Although i cant vouch for 20 year old siemens, my siemens modules (14 yr
old sp-150s) had an intermittent connection develop between the stainless
ribbon that exits the back sheet and the terminal where the blocking diodes
connect (3 diodes). There used a spot welder to join the materials. This
The batteries are good. We are going to try some
custom settings. This CC works a bit differently
than most, and the problem may be in the duty
cycle, IE, how much time the pulses are on vs off.

Hello Rebekah,I have had no luck in getting the older style without AC required either.I agree that these newer devices that require AC are better performers.Some of these(most ?) have a built in anti-freeze protection scheeme.It is made from a ceramic heating element(HI-WATT RES.) that will come
