Solar, fleet and site-power applications for G186120

The battery-integrated system can support high-power EV charging, compatible AC loads and approved bidirectional grid projects.

G186120 Solar & off-grid operations application
Use case 01 · Solar & off-grid operations

Store daytime solar energy for later vehicle or site use.

G186120 separates energy collection from energy use. At sites without a reliable utility connection, the system can store available solar or approved AC input and deliver controlled output when vehicles or compatible site loads need it.

  • Optional solar PV input
  • High-power discharge on demand
  • Project-sized energy and runtime

G186120 Fleet peak-valley operation application
Use case 02 · Fleet peak-valley operation

Use lower-tariff charging periods to support peak fleet demand.

The battery can recharge during lower-tariff periods, then support high-power vehicle charging when depot demand and electricity prices rise. This helps reduce the charging peak and gives operators more control over daily energy cost.

  • Lower-tariff energy storage
  • Peak-period EV charging
  • Controlled depot power demand

G186120 AC loads & grid connection application
Use case 03 · AC loads & grid connection

Supply compatible AC loads and approved grid-export projects.

Beyond vehicle charging, G186120 can be configured to supply compatible AC loads. Project-specific export back to the grid requires a bidirectional PCS, protection design, local grid-code compliance and utility approval.

  • Compatible AC-load support
  • Bidirectional PCS configuration
  • Grid-code and utility review

Project questions

G186120 application FAQ

Key configuration points for solar charging, peak-valley operation, AC loads and grid-connected projects.

Can G186120 charge from solar power at an off-grid site?

G186120 can be configured with optional solar PV input to store energy during daylight hours and deliver controlled output later. PV voltage, array size, charging power and required runtime are confirmed for each project.

Can G186120 charge off-peak and discharge during peak demand?

Yes. The battery can recharge during lower-tariff periods and support high-power EV charging when depot demand or electricity prices rise. The operating schedule depends on the local tariff, site load and battery configuration.

Can G186120 power AC loads or export electricity to the grid?

It can be configured to supply compatible AC site loads. Export to the grid is project-specific and requires a bidirectional PCS, protection design, local grid-code compliance and approval from the relevant utility.
