Enclosure Ratings: Polymeric, NEMA Type 3R
Elevation: 3000m (9843ft)
RH: 100%
OVC II, Pollution Degree 1
Maximum Short-Circuit Current Rating (SCCR): 20A Per input feed.
Maximum Sum of the short circuit current (SCCR): 50A
Maximum Overcurrent Protection rating: 16A per feed (located at the Maximizer, 50A breaker located at the
ESS)

Enclosure Type: 3R

Conditions of Acceptability:

(1) The Maximizer Hub shall be installed only with Lunar Maximizers and Lunar Inverters.

(2) Total output current shall not exceed 50A (dc) Max.

(3) Upstream protection provided by Lunar Maximizer and output overcurrent protection and disconnect are
provided by Lunar Inverter.

(4) Drain openings must meet the CSA C22.2 94.2 and UL50E openings requirement outlined for Type 3R
enclosure.

(5) Up to a maximum of 3 strings can be connected to a single Maximizer Hub.

(6) To be used only with Lunar Maximizer and Inverter listed under 80136899 and 80121274 respectively.

(7) Watertight compression connector and water resistance gland must be used for conduit connection.

(8) Conduits for input and output cabling shall be mounted on either side or both sides and not on the top or the
bottom of the enclosure.

(9) Electromagnetic immunity to be evaluated in the end system.

(10) Conduit and Cable Entry to be evaluated in the end installation (Refer to installation manual).

(11) The Max Input Current per terminal is labeled as 40A. However, in the Lunar System the Max current per
PV String is 16A and three of such strings can be connected in parallel contributing to the combined string
with Max output of Maximizer Hub of 37.5A which is an Input to the Lunar Inverter.

(12) Max input current(dc) per PV String shall be 16A which is limited by Maximizer.
