This Box Tames it.\u003c\/span\u003e\u003c\/h5\u003e\n\u003cp\u003eA small wind turbine is the easiest thing in the world to wreck a battery bank with. Its voltage climbs with every gust, it keeps charging after the bank is full, and on a wild night with nothing loading it up the rotor just winds up and up. The controller is the half of the system that stops all of that: it takes the turbine's three-phase output, turns it into a clean DC charge, holds the battery inside its window, shunts the surplus into a dump load when the bank is full, and pulls the turbine up short when it over-speeds.\u003c\/p\u003e\n\u003cp\u003eThe WCMD is the pure-wind MPPT controller we fit to our own small turbines, the M-400, M-600, M-800 and X-300, sold here on its own for anyone who already has a turbine and needs the box that goes with it. Three versions, one per battery voltage: the \u003cstrong\u003eLWCMD400W-12V\u003c\/strong\u003e for a 12 V bank, the \u003cstrong\u003eLWCMD800W-24V\u003c\/strong\u003e for 24 V and the \u003cstrong\u003eLWCMD800W-48V\u003c\/strong\u003e for 48 V. Every one ships with its matched dump-load resistor in the box. It is part of the unit, not an extra.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStraight Up About the Numbers:\u003c\/strong\u003e the 400 W and 800 W in the model names are the turbine sizes each controller is built to sit behind, not power the controller makes. A controller makes nothing on its own; what reaches the bank is whatever the wind gives the turbine. And the manufacturer has not published a maximum charging current in amps for this series. What it does give you is a charge limiter you set yourself: enter the bank's capacity in amp hours on the screen and the controller caps charging at 0.3 times that figure. Cable and breaker sizing is your electrician's job, from your system, never from the number in a product title.\u003c\/p\u003e\n\u003ch5 style=\"text-align: center;\"\u003e\u003cspan style=\"color: #00aaff;\"\u003eWhat it Solves\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul style=\"margin-left: 2em; padding-left: 0;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003cspan style=\"color: #7fd4ff;\"\u003eThe Breeze That Never Quite Charges:\u003c\/span\u003e\u003c\/strong\u003e when the turbine's voltage sits below the battery's, the boost stage lifts it to charging voltage instead of letting it idle.

That is how people end up sizing breakers off a guess. The controller does have a user-set limit: enter the bank's capacity in amp hours and it caps charging at 0.3 times that. Your electrician sizes cable and protection from your turbine, your cable run and your bank, not from a product title.

The manufacturer's own words are that \"controller\" means the controller unit plus the dump load, and the dump load does not need to be bought separately.

The printed series datasheet shows 80 V against the 24 V column; we asked the manufacturer which was right, and their written answer was that 180 V applies to the 24 V and 48 V versions and the 80 V figure is for the 12 V version only.

A small turbine of this class makes three-phase AC, and the rectifier inside the controller turns it into DC for the battery. The three wind terminals take the three phases in any order.
