Answers to common questions about EVGREEN chargers, Power Balancing, installation, Cloud & App, and support.
EV Chargers
What type of EV chargers does EVGREEN offer?
EVGREEN offers smart OCPP Level 2 EV chargers for home, rental properties, workplaces, and small commercial charging locations.
Available connector options include:
-
J1772
-
NACS
EVGREEN chargers are designed for smart monitoring, remote management, Power Balancing, and EVGREEN Cloud & App connectivity.
What charging power does the EVGREEN charger support?
EVGREEN Level 2 chargers support adjustable charging current up to the charger's rated maximum.
Actual charging speed depends on:
-
Vehicle onboard charger capability
-
Circuit size
-
Installer current setting
-
Available electrical capacity
-
Power Balancing conditions
Can EVGREEN chargers be hardwired?
Yes.
EVGREEN chargers may be installed as:
-
Hardwired
-
NEMA 14-50 plug-in, depending on model and configuration
A qualified electrician should perform the installation.
Can I use an EVGREEN charger outdoors?
Select EVGREEN chargers and installation components are designed for indoor or outdoor use.
Always follow the product installation manual and applicable electrical codes.
Power Balancing
What is EVGREEN Power Balancing?
EVGREEN Power Balancing automatically monitors available electrical capacity and adjusts EV charging power when household or building electrical demand changes.
This can help reduce the need for unnecessary electrical service upgrades.
How does Power Balancing work?
The Dynamic Energy Meter measures the property's electrical load.
When electrical demand increases, EV charging power may automatically decrease.
When more power becomes available, charging can automatically increase again.
The system may operate as:
Full Power → Reduced Power → Pause → Resume
Can Power Balancing work with more than one charger?
Yes.
EVGREEN systems can combine:
-
Dynamic Load Management
-
Multi-Charger Power Sharing
Available charging capacity can be shared between connected chargers.
Can I install an EV charger on a 100A electrical service?
In many homes, yes, depending on the existing electrical load and installation conditions.
A Dynamic Energy Meter and Power Balancing system can help manage charging within the configured electrical service limit.
A qualified electrician should evaluate the electrical system before installation.
What about a 200A electrical service?
A 200A service generally provides more available capacity for EV charging and can support multiple chargers depending on existing building loads and system configuration.
Dynamic Energy Meter
What does the EVGREEN Dynamic Energy Meter do?
The meter measures electrical usage and sends real-time load information to the EV charging system.
This information allows EVGREEN Power Balancing to adjust charging power automatically.
Where is the meter installed?
The meter is normally installed near the main electrical panel or distribution panel.
Current transformers, or CTs, measure the electrical current entering or leaving the monitored circuits.
Does the meter connect to the internet?
The meter communicates locally with the EVGREEN charging system.
Internet connectivity may be provided through the charger or EVGREEN Cloud, depending on the system configuration.
Installation Kit
What is included in an EVGREEN Installation Kit?
The exact contents depend on the selected kit.
Installation Kits may include:
-
Electrical conductors
-
Conduit
-
Connectors
-
Breaker components
-
NEMA 14-50 receptacle
-
Weather-resistant enclosure
-
Installation hardware
Can I install the kit myself?
EV charger circuits involve high-voltage electrical work.
Installation should be performed by a qualified electrician and must comply with applicable electrical codes and permit requirements.
What is the difference between a hardwired kit and a NEMA kit?
A hardwired installation connects the charger directly to the branch circuit.
A NEMA installation uses a compatible receptacle and plug.
The appropriate installation depends on the charger, circuit rating, location, and local electrical requirements.
Panel Upgrade Kit
When might I need a panel upgrade?
A panel or electrical service upgrade may be considered when:
-
Existing electrical capacity is insufficient
-
The panel has limited breaker space
-
Existing equipment is outdated or damaged
-
Additional electrical loads are being added
-
Local code or utility requirements require an upgrade
Power Balancing may help some properties add EV charging without a complete service upgrade.
Does EVGREEN install electrical panels?
EVGREEN provides compatible equipment and system solutions.
Panel replacement and electrical service work must be performed by qualified electrical professionals and may require permits and utility coordination.
Do I still need Power Balancing after upgrading to a 200A panel?
Power Balancing can still be useful after an upgrade.
It can help manage:
-
Multiple EV chargers
-
Large household loads
-
Workplace charging
-
Available charging capacity
-
Peak electrical demand
EVGREEN Cloud & App
What can I see in the EVGREEN App?
Depending on the system and account type, users may be able to view:
-
Charger status
-
Charging status
-
Charging power
-
Session energy
-
Charger availability
-
Power Balancing status
-
Multiple charger activity
Hosts may also have access to property, driver, authorization, and charging-income features.
Can a property owner manage multiple chargers?
Yes.
EVGREEN is designed to support home and small-property charging systems with multiple connected chargers.
Can I authorize specific drivers?
Yes.
Hosts may authorize charging access using supported methods such as:
-
EVGREEN App
-
RFID
-
Assigned users
-
Payment authorization where enabled
Can charging be free for some users and paid for others?
Depending on the account and site configuration, hosts may be able to provide free charging to approved drivers or enable payment for other users.
OCPP & Connectivity
What is OCPP?
OCPP stands for Open Charge Point Protocol.
It is an open communication standard that allows compatible EV chargers to communicate with charging management software.
Why does EVGREEN use OCPP?
OCPP helps provide:
-
Remote charger monitoring
-
Charger status information
-
Smart charging control
-
Diagnostics
-
Firmware management
-
Charging session information
-
Cloud integration
What happens if Wi-Fi is temporarily unavailable?
Available charger functions during an internet outage depend on the charger configuration and operating mode.
Local charging and local Power Balancing may continue where supported, while Cloud and remote functions may temporarily be unavailable.
Multiple Chargers
How many EVGREEN chargers can be connected together?
System capacity depends on the specific installation and EVGREEN configuration.
Home and small-property systems can be configured for multiple chargers with shared available electrical capacity.
Will all chargers charge at full power at the same time?
Not necessarily.
When multiple vehicles are charging, available electrical capacity may be automatically shared among the active chargers.
