NOTE
Damage to the Renogy inverters due to reverse polarity is NOT covered by warranty.
The input terminals of the inverters have large capacitors connected to them. Once
a positive and negative wire are connected to the terminals, it will complete the
circuit, and commence drawing a heavy current momentarily. As a result, there may
be a sparking occurring even if the inverter is in the off position. To minimize
sparking, it is recommended that the user have the appropriate size wire feeding into
the inverters and/or install an external fuse leading into the inverter.
Do not over-tighten the M8 DC Terminals. The recommended torque is 12 ~ 16N-m
/ 105.9 ~ 141.5 lbf-in
Grounding
DC Wiring
The Renogy Pure Sine Wave Inverters are suitable for 12V battery bank systems ONLY.
Not following the minimum DC requirement will cause irreversible damage to the unit.
WARNING
At no point should the chassis ground and the neutral conductor of the inverter be
bonded. Bonding the chassis ground and the neutral conductor of the inverter or
connecting the inverter to household or recreational AC distribution wiring will
damage the unit and void the warranty.
WARNING
CAUTION
Be careful of the positive and negative poles. Reversing the poles might cause
permanent damage to the inverter. It will surely blow the internal fuse.
If available, the chassis ground lug should be connected to a ground point such as a vehicle
chassis or boat grounding system. In fixed locations, connect the ground lug to earth ground.
The connections to ground must be tight and against bare metal. Whether using the inverter in
a mobile application, such as an RV, or in a building, grounding is highly recommended. The
recommended wire size for grounding is 14AWG (1000W), 12AWG (2000W), and 10 AWG
(3000W) insulated copper strand wire.
The neutral (common) is not bonded to the chassis ground. Therefore, when chassis is
connected to ground, the neutral conductor is not grounded. At no point should the chassis
ground and the neutral conductor of the inverter be bonded. Bonding the chassis ground and
the neutral conductor of the inverter or connecting the inverter to household AC distribution
wiring will damage the unit and void the warranty. For more information regarding grounding,
users and/or installers must consult with the Local and National Electric Codes (NEC) for more
specific grounding regulations and suggestions as they can change per scenario.
CAUTION
Do not over-tighten the M4 Ground Screw. The recommended torque is 1.5~2.0N-m
/ 13~18.2 lbf-in
