Storage

PCS is a set of software-enabled features and settings that installers can configure during installation and commissioning. These are greatly expanded with the 3rd generation of the Enphase Energy System. 

At launch in June 2023 the Enphase Energy 3.0 system will support: 

• Main panel upgrade avoidance for 

1. Grid forming configurations with IQ Battery 5P and IQ8 Microinverters as well as 10T/3T and IQ8 
2. Grid tied configurations with IQ8 Microinverters 

• Increasing battery capacity for  

1. Grid forming configurations with IQ Battery 5P 
2. Grid tied configurations with IQ Battery 5P 

• Aggregate power export control to meet utility requirements for 

1. Grid forming configurations with IQ Battery 5P and IQ8 Microinverters 
2. Grid tied configurations with IQ8 Microinverters 

• Import-only mode for IQ Battery 5P to ensure NEM integrity and avoid feeder transformer upgrades. 

1. The specific details of the use case and site are key to determining which Enphase product combination would currently best support NEM 3.0 based on the 150% of Storage / PV kW rule 
    

2. Both IQ Battery 10T/3T and IQ Battery 5P are good solutions for NEM 3.0.  
    

3. IQ Battery 5P solution: 
   IQ Combiner 5/5C + IQ8 PV + IQ Battery 5P with PCS for PV and Battery Oversubscription and Export Only mode 
   HW and basic system available at launch i.e., SG4 
   PCS for export only in Q3 2023 
   PCS for PV + Battery Oversubscription to avoid main panel upgrades Q4 2023 
    

4. IQ Battery 10T/3T solution: 
   IQ Combiner 4/4C + IQ8 PV + IQ Battery 10T/3T with PCS for PV and Battery Oversubscription and Export Only mode 
   HW and basic system available at launch i.e., SG4 
   PCS for export only in Q3 2023 
   PCS for PV + Battery Oversubscription to avoid main panel upgrades 1H 2024 

1. IQ Battery 5P is compatible with all IQ Series Microinverters. IQ Battery 5P can also be installed with M Series Microinverters in states that have not yet adopted IEEE 1547:2018.  
    

2. IQ Battery 5P works exclusively with IQ System Controller 3/3G and IQ Combiner 5/5C. It is not compatible with prior generations of Enphase Energy System equipment which use wireless Zigbee communication including IQ Battery 3/10/3T/10T, IQ System Controller 1/2. This is because the new components require Control cabling between components instead of wireless. 
    

3. Older IQ Combiners and standalone IQ Gateways can be made compatible with 3rd generation components by adding the Comms Kit 2 accessory (to be released later this summer).

For the best performance, we recommend using only Enphase Control cabling (CTRL-SC3-NA-01). The Enphase Control cable is UL approved and can be run alongside the AC cables inside conduit runs.  
Commissioning times and system performance promised by Enphase are dependent on using the Enphase Control cable. 

The products will be available in all 50 states and Puerto Rico. The product is not yet released in Canada, Mexico, or other US territories. Additional details on the releases for these markets will be available soon.  Please contact your local Enphase Sales representative if you are interested in additional details.   

The IQ Battery 5P was designed by Enphase Engineering teams in California, New Zealand and India. Micro inverters in the 5P are manufactured worldwide.  The product is currently assembled in China. 

One of the Enphase key values is quality. Enphase has demonstrated its commitment to quality through eight generations of microinverters and two prior generations of battery products. The learnings associated with these products has enabled Enphase to offer another industry-leading warranty with our 3rd generation battery product.  

A universal hold down kit will be included with all IQ System Controller 3/3G units enabling installers greater freedom in sourcing compatible breakers. 

The PV:Storage ratio is determined by the model of microinverter in use, so accurate sizing calculations should be completed (see latest Enphase Energy Planning Guide).  When used with IQ8 Microinverters, IQ Battery 5P has no solar-to-storage ratio limitations.  

M Series sites require use of a legacy Envoy S Metered. In states that have not yet implemented IEEE 1547:2018, you can add a Comms Kit 2 accessory (to be released later this summer) to solar only sites with M Series Microinverters in order to add IQ Battery 5P.  
If the property is in a U.S. state that as adopted IEEE 1547:2018, the site cannot add IQ Battery 5P without first upgrading to an IQ Microinverter system inclusive of an IQ Combiner (which is IEEE 1547:2018 compliant).  

No, Enphase is not planning to ship a cover for 2 units. IQ Battery 5P units ship in the same box as their cover, reducing the possibility of damage and simplifying inventory management compared with IQ Battery 10T.  
Enphase IQ Battery 5P is UL9540A certified and, where allowed by local code, can be installed 3 inches apart to minimize the storage footprint. Additionally, installers can leverage the new Enphase pedestal (to be released later this summer) for floor mounting in front of a wall mounted battery. 

Existing system owners can add more IQ Battery 3/3T and 10/10T to their system without upgrading any other components.

IQ Battery 5P uses high speed wired connections to communicate with other Enphase Energy System equipment. This allows for faster performance, improved commissioning, greater installation distances, and a better installer and homeowner experience.  IQ Battery 5P is therefore not compatible with any prior generations of the Enphase Energy System which use Zigbee wireless communication.
