One of the most important criteria when purchasing an inverter
is its efficiency.
The higher the efficiency, the lower the losses that are
incurred when converting direct current produced by the solar modules into alternating
current. SMA has set a new record for transformer-based units by achieving a
maximum efficiency of 95.6 %.
As well as ensuring the maximum effectiveness for the OptiCool®
active cooling system developed by SMA, an all-new, extra heavy duty extruded
aluminium housing with a double-chamber design also safely protects the electronic
components from the wind and weather.
Features:
- Easy plant design and reduced installation costs
- SMA grid guard®
- Diagnosis and communication via Powerline Communication,
radio transmission or via data cable (RS232 or RS485)
- Extended temperature range –25 °C to +60 °C
- For outdoor and indoor installation
- Connection on the AC- and DC-side with connectors
- Surge voltage protection with integrated thermally monitored
varistors
- With OptiCool® ventilation system – suitable
for outside installation
