SI 3300
Solar Inverter SI 3300
The solar inverter SI 3300 from Delta has a peak efciency
of 96.0%, so it rightfully occupies rst place among invert-
ers with transformer (see Photon Solarstrom magazine
05/2008).
The elegant and compact design of the casing and low
noise characteristics of the SI 3300 makes this solar
inverter from Delta look good even in living areas. You can
of course mount it in protected outside areas as well since
the IP65 casing is dust-tight, completely safe to touch
(shock proof) and protects the unit from spray water from
any direction.
Highly efcient and reliable, with its intelligent MPP track-
ing, the SI 3300 extracts maximum performance from your
solar cells under all operating conditions.
Using the wall bracket supplied, mounting Delta’s SI 3300
is no problem, even for the private user.
