Huh? The equipment does not "take" or "draw" anything. The electrical pressure
of the source, called voltage, forces electrons through the load. Electrons per
unit time are called current. The current is only limited by the resistance of
the load, in accord with Ohms Law. The resistance of the load
Because it is not 80 amps current flowing, it is a capacity of 80 amps.
Think of it this way. Your toaster is plugged into an outlet that is
powered by the grid. The grid has infinite capacity. Why doesn't your
toaster explode? Because it takes the current it needs. Now, increase the
voltage and yo
I used 80-90A estimated because our
combination of high elevation and dry air makes 1,200 W/m2 quite
common.

Any reviews/suggestions of the rain stops made specifically for Silicon Energy

Wrenches,
For years, Direct Power has sold used GNB Absolyte II sealed
batteries, shipped in from Canada from telecom use. The batteries
have a pretty good reputation - at least, I haven't heard of short
remaining lifetimes from customers who have bought them.

Allan,
Just to add to Larry's post, a 100W "12V nominal' module would put out about
5.9A, assuming that it's really a 100W module and has a Vmp of 17VDC. So 12 of
them should be about 70-71A. The C-40 is not MPPT, so there is no amperage
boost.
Luckily, the C-40 is actually rated for a max inp
Allan,
12 100 watt modules are more likely to be about 60-70 amps. With all the losses
involved in a poorly designed DIY system (like most of them), I would expect to
see more than 25% power loss. Perhaps that is why the controller lasted.
There is no current limiter in the C series controller
Wrenches,
Sometimes I encounter a situation that I have never encountered,
simply because it's so far beyond normal limits that I would never
try it to find out what would happen. Here's one.
A did-it-myself customer called me for batteries for his system. I

This is all about reducing risk. I include sections specifying that
additional charges may apply if:
-We are required to appear at a planning commission, historical
preservation or other committee or create additional documents to respond

Although, not a specifically a wrenching question, writing solid paperwork
directly leads to turning the wrench.
I am looking to update my contract small print. I'm updating a contract
that has worked for 35 years, but it is highly reliant on a firm hand
shake, so to speak.
