Battery technology independent
Add storage without new grid interconnect agreement
Works with large or small storage projects
Easily interfaces with third-party energy management systems
High DC ratios
Ampt optimizers enable inverters to accept DC ratios of 2:1 or more
Maximize energy generation
Deliver energy to battery and inverter simultaneously
Optimized PV Array
Fewer cables and combiners saves on equipment and labor costs
2 MPPTs per string increases lifetime system performance
Improved O&M with string-level data
Lower Cost Storage Architectures with Ampt
Ampt’s Direct-to-Battery technology allows the optimizer, battery, and inverter to share the same DC bus without additional charging equipment dedicated to the battery.
Minimizes charging hardware to lower cost
Fewer power conversions to improve efficiency
Optimized PV array
Ampt optimizers allow the DC bus to operate at a higher fixed voltage. This increases the power density of both the charging converter and inverter to lower equipment cost per watt while increasing the solar+storage system efficiency.
Lower cost per watt charging converter and inverter
Higher efficiencies with fixed DC bus voltage
Optimized PV array
Direct-to-BatteryTM Detailed View
EMS is the primary system controller
Controller sends signals to the battery, inverter, and optimizer (via the CU)
String Optimizer performs MPPT to deliver more energy from the array
The output voltage of the optimizer follows the battery bus during charge and discharge
The CU send commands it has received from the Controller to dynamically curtail optimizer output as determined by the EMS
Direct-to-ConverterTM Detailed View
EMS is the primary system controller
Controller sends signals to the battery, inverter, and charging converter
String Optimizer performs MPPT to deliver more energy from the array
The optimizer enables the DC bus to operate at a fixed high voltage
The charging converter and inverter have a higher power density to lower cost per watt
