...what's your charge current, battery capacity, type of battery, charge set points....
"Got a minute? I'll tell you everything I know!"
Today my system (because it might be different tomorrow) has a funny interation between the turbine and the solar panels, but I'll start in pieces and then put them together
Batteries: GNB Absolyte IIP 90A11, 6 cells per tub, 2v each X 4 sets + 24 Cells that I currently have configured for 24V in 2 strings. The data plate rating for each 12V set is 440AHr at 8-hour rate, from full to a 1.75 Volt-per-cell discharge.
Turbine: 8-foot diameter 3-bladed wooden rotor, driving a converted 3-phase motor. The motor/alternator was bench tested up to 1kw in various conditions to simulate using Star, Delta, and independently recitified phase connections. Currently I observe a peak 400 Watts over a large range of wind speeds in Star, due to stalling the blades, but I can switch it to IRP (I call it "Jerry"-rigged) and it will run much faster RPM but produce much more power (have seen peaks over 1kw). The conclusion is that the rotor is too small to match the generator, however I'm getting by and it's fun flipping it into "High gear".
Solar: Two panels that would be better suited on a MPPT controller. Too bad for me. Data plate MP at 17.3V or so and 7.4 Amps. Connected in series the string voltage would be over 34 volts but they are clamped to 24-28 by the battery. I've seen peaks of 7 Amps but only at noon on a clear day, when the panels are perfectly aligned with the sun's elevation.
Charge Controllers - Wind: Tri-Star TS-60 with a 1200W dump load. Sorry I forget the exact settings but they are around 27.6V. Equalization is off/manual/disabled. The dump load resistors are inside the box so that the heat is used.
Charge Controllers - Solar: Xantrex C40 with simple solar regulation. 27.4V float and 27.6V bulk charge. No equalization.
The batteries are in an insulated box outside. Temperature in side lags by a few degrees but usually not much warmer than outdoor temperature. Due to very cold temperatures, I have an odd way to regulate voltage and temperature in the box: The Xantrex CC is temperature regulated, but the Tri-Star is not. This causes some useful effects, but the point is to
not overcharge the battery. ON a sunny day, solar energy from the panels will not be regulated down by the PWM circuit because the Xantrex CC wants the battery voltage to float at 27.4-27.6V
plus 1.5 Volts or more. Before this can happen, the Tri-Star kicks in. It's not temp regulated, so the solar energy runs out the dump load instead of raising the voltage above 27.6V. Whatever electricity is needed by the batteries, they get, whatever isn't can warm up the box a little. On windy days a lot of the energy is shed as heat in the box. It can get 20C warmer in there than outisde.
Don't tell anyone I do this. They'll come up with some obscure reason why I shouldn't.
