Solar Andalucía

The inverter is the heart of your system. This unit generates the standard household 240 Volt AC current, as in a grid-connected house. It enables you to run normal electrical appliances such as lights, television, vacuum cleaner, washing machine, Internet connection and stereo. A few of these appliances can be obtained for 12/24 Volt DC (this is what your system generates without the inverter), but due to the size of the 12/24 Volt market the products are expensive, so the inverter is actually a better deal. Also the cost for wiring drops dramatically for 240 Volt Alternating Current compared to the bigger cables needed for DC loads.

The catch with these inverters is that many will not be as efficient on low loads, which often is the case in everyday usage. Furthermore many inverters give a rough alternating current, making more sensitive equipment fail.

Sine Wave Inverters

We have discarded the cheaper products, featuring pure sine wave Inverters from Solener and Victron Energy. These products might increase the initial investment, but the true (and far more economical) value of the excellent product will be obvious after a few years usage. With a high conversion efficiency, durable and proper designed, these machines will yield even higher watts in peaks than stated. They rarely fail if ever, enabling you to enjoy your solar system without thinking too much on load capacity and possible power failure. Cheaper inverters can be obtained from the Internet, but we do not recommend this, as frequent failure and replacement of burned out units makes them less economical. We have inverters in the range from 600 – 3000 Watts – all pure sine wave! We use Inverters which have been designed specifically for solar energy applications and which are microprocessor controlled.

Tech stuff
PWM modulation with full bridge, complying with the applicable standards about harmonic content and EMI-RFI compatibility. They are protected against short circuit, overload, overheating, over voltage, transitories and polarity inversion. Polarity inversion does not destroy any fuses as in inverters from other manufacturers.

Some versions have an input control which allows the inverter to be remotely switched on and off. Other versions have buttons, allowing the configuration of the device depending on the user requirements. All Solener inverters but the S250 have a LCD display, which can display information in Spanish, English, French, German and Portuguese as configured in the main menu.

In some versions the Inverter reconnects automatically when the conditions that caused the fault disappear (low or high battery, overheating, external control). It does not reconnect automatically in case of overload or short circuit (optionally, it can restart after a few minutes).

The tracking threshold can be adjusted using a potentiometer located in the front from 0 Watt (always connected) to 60 Watt. If the connected load power is lower than that adjusted with the potentiometer the light will blink with a frequency of 1 Hz. This adjustment is necessary because the applications are very wide and the installation cabling may also cause power drops (by capacity and by radiation).
