Power Optimiser
PV power optimisation at the module level
- Specifically designed to work with SolarEdge inverters
- Detects abnormal PV connector behavior, preventing potential safety issues*
- Module-level voltage shutdown for installer and firefighter safety
- Superior efficiency (99.5%)
- Mitigates all types of modules mismatch- loss, from manufacturing tolerance to partial shading
- Flexible system design and compatible with bifacial PV modules for maximum space utilisation
- Faster installations with simplified cable management and easy assembly using a single bolt
- Next generation maintenance with module safety.
Labeling the system
For SolarEdge systems where AS/NZS5033:2014, clause 2.15 applies, when installing power optimisers with a rated input power exceeding 350Wp, a label must be affixed to each power optimiser as outlined below.
Secure the label to the mounting bracket of the power optimiser, ensuring the arrow is directed towards the DC input connection. If the optimiser bracket faces the roof, position the label on an alternative visible location on the optimiser.
De-energizing the circuit
When using power optimizers with a combined input power exceeding 350Wp, and in order to comply with AS/NZS 5033:2.1.5 (c), follow these steps before performing any work on the system’s PV arrays, including handling modules and optimizer connections:
- Switch the inverter ON/OFF switch to the OFF position.
- Turn the inverter Safety Switch to OFF.
- Use an appropriate DC clamp meter to check for current flow within the input circuits of the power optimizer to confirm the circuit has been de-energized:
- If no current flow is detected, the circuits are de-energized, and it is safe to disconnect the DC inputs.
- If current flow is detected (or if a DC clamp meter is unavailable), cover the associated module(s) with an opaque material before disconnecting the DC inputs to de-energize the circuits.
