• Solar Watts is for on grid.
o System waits to turn on smart load until sufficient PV power is produced (when on grid).
• AC Coupling Settings (For Micro Inverter Input)
o To use the Grid input breaker as a micro inverter AC coupled input, check the “For Micro inverter Input”
box (this feature will also work with “Grid-Tied” Inverters)
▪ 13kW = Maximum combined input to Sol-Ark (AC+DC)
• Best: 3kWAC + 10kWDC
• Good: 4kWAC + 9kWDC
• OK: 2kWAC + 11kWDC
• OK: 5kWAC + 8kWDC
• OK: 6kWAC + 7kWDC
• OK: 7kWAC + 6kWDC
• Grid Setup
o Limiter
▪ Grid Sell: maximum watts sold to grid
▪ Limited To Home: Limits power produced by the system
to match the demand of the home
▪ Limited To Load: Limits power produced by the system to
match the demand of connected loads
▪ Time Of Use:
• Time: When the system will sell batt/PV power to
the grid or home
• Power(W): Max watts to be sold from the battery at each time
• Batt: The battery voltage or % at which the system will limit selling to the grid or home
from the battery. The system will drain the battery until that percent/voltage is reached.
• Charge: Enables grid charging during a selected period. PV will always charge to 100%.
• For Examples: See Page 37
▪ Note: This mode requires Grid sell / limited to home be enabled.
▪ Note: If you need the batteries to never charge from the grid, uncheck the “Grid Charge” box
under the charge tab of the battery menu (see page 29).
o Sell Control
▪ General Standard: uses Protect Parameters in table
▪ UL 1741 & IEEE1547: Enables sell compliant functionality
▪ UL1741SA: Enables wider Freq, Voltage, and PowerFactor
▪ GEN connect to Grid Input: Must be set if Generator is
connected to AC Grid breaker
o Grid Input
▪ Grid Frequency: Select the frequency of the grid
connected to the system
▪ Grid Type:
• 220V Single Phase (Call us before using)
