Description

Specially designed for industrial and outdoor applications, the 140A solar side Steca Power Tarom 2140 Charge Controller 12-24V comes with an IP 65 casing made of powder-coated steel. This 70A (on the load side) solar charge controller is capable of regulating large systems at two voltage levels (12 V, 24 V). The Steca Power Tarom is based on the technology of the Steca Tarom controller. When connected in parallel, several controllers from this series can be operated via a standard DC bus in a simple solar home system or a hybrid system.

Majority of the German Steca off-grid solar components are high-performance charge controllers designed to protect the batteries in your system at a reasonable price. Robust and effective, these charge regulators are perfectly suited to small and medium off-grid solar panel systems where the input voltage is not too much higher than the system voltage.

There are three different types of solar charge controllers, they are:
  • Simple 1 or 2 stage controls.
  • PWM (pulse width modulated)
  • Maximum power point tracking (MPPT)
Add up the total watts of solar panels and divide by either 14.4 for 12-volt systems 28.8 for 24 volts or 58.8 for 48-volt battery banks. This will give you maximum output amps from the controller. If you don’t want to waste output in heat, size the controller at around two-thirds the rated output of the controller.

Charging your battery at 12 volts and 20 amps will take five hours to charge a 100 amp hour battery. By multiplying 20 amps by 12 volts, 240 watts is how big of a panel you would need, so we’d recommend using a 300w solar panel or 3 100 watt solar panels.

Take the power produced by the solar panels and divide by the voltage of the batteries. For example: Example: A solar array is producing 1 kw and charging a battery bank of 24V. The controller size is then 1000/24 = 41.67 amps.

A wind or solar pv charge controller‘s primary function is to protect your battery bank from overcharging. It does this by monitoring the battery bank—when the bank is fully charged, the controller sends energy from the battery bank to a dump (diversion) load.

You typically want to make sure you have a Steca charge controller that is large enough to handle the amount of power and current produced by your panels. Typically, Steca charge controllers come in 12, 24 and 48 volts. Amperage ratings can be between one and 60 amps and voltage ratings from six to 60 volts.

The exception to this rule is when using solar panels smaller than 5 Watts. Select a Steca charge controller that is compatible with the system voltage. The standard configurations are 12, 24, and 48 volts. If you are wiring your batteries for 24 volts you need a Steca charge controller that is rated at 24 volts.
