Ampt String Optimizer V1500 Series
Installation Manual: 57070012-1H
Mechanical Installation Best Practices
•
Store optimizers in a sheltered location that is protected from weather exposure. Optimizers
damaged by water due to improper storage are not covered under warranty.
•
Ground according to local codes using the grounding stud or a listed bonding washer.
•
Ensure that optimizers are oriented with connectors facing down unless otherwise specified by Ampt.
•
Keep optimizer in a covered location and free from pooling water.
•
If possible, keep the top side of optimizer free from obstructions to maximize the radio signal.
•
Leave connector caps in place until they are ready to be connected to protect the optimizer from
water and debris ingress.
•
Leave space between mounted optimizers to allow for air circulation and cooling.
•
Make sure there is enough slack on the input and output wires to ensure that they do not cause
strain on the optimizer bulkhead connectors.
•
If installed on a tracker system, keep wires free from abrasion and leave enough slack in the wires to
account for tracker movement.
•
DO NOT
o
Store optimizers outdoors without protection from weather and water ingress.
o
Transport optimizers that are removed from packaging.
o
Mount optimizers with connectors facing upwards.
o
Mount optimizers directly to a solar module frame.
o
Drill into optimizer frame to expand mounting holes.
Electrical Commissioning Best Practices
•
Be sure to only use Amphenol connectors on input and output wires that are connected to optimizer.
•
Only use Amphenol crimping tool and disconnect tool on cabling and connectors.
•
Ensure there are no ground faults on input strings.
•
Test voltage and polarity of input strings and optimizer output.
•
If an optimizer input will have two or more PV strings in parallel, make these connections before
connecting the optimizer input.
•
Connect in the following order: Input 1, Input 2, Output.
•
Always use a current clamp to ensure there is no current present before disconnecting
outputs/inputs.
•
If disconnecting unit: disconnect Output first, then Input 2, then Input 1.
•
Configure inverter settings appropriately according to the project design.
•
DO NOT
o
Connect output of optimizer before connecting inputs.
o
Disconnect under load.
o
Disconnect optimizer connectors without checking for current first.
o
Disconnect optimizer inputs before output.
o
Operate optimizer with only one input.
o
Use improper disconnecting tools on the connectors.
