What is the difference between Ac coupling vs dc coupling ?
Traditional off-grid systems are DC-coupled, with battery bank charged by connecting PV modules to a large solar charge controller, which regulates current and voltage.
With AC coupling, an on grid solar inverter is wired directly to the AC loads panel. The battery bank powers the DC-to-AC inverter, the solar production is fed to the AC loads panel, and the extra power from the AC bus is converted to DC to charge batteries.
Ac-coupling offers more advantage than DC coupling in that it gives the user much more flexibility in system configuration.
Traditional off grid inverter chargers are not designed to regulate the charge from an AC coupled system.
These power inverters normally have no battery over voltage protection when they are in inverter mode.
Thus they are unable to prevent battery from overcharge in inverter model when extra power is feed from grid tie inverter to their AC output.
Our 15000 watt power inverter features Dry Contacts Providing Frequency Switch Between 60Hz / 62.5Hz as the secondary charge control of on grid inverter .
It can control excess energy from the GT batteryless inverter when the battery bank reaches a voltage within the manufacturer’s limit.
To accomplish this, you can use a voltage-controlled relay to close the dry contact to switch the output freq from 60hz to 62.5Hz, shutting off the grid tie inverter system.
Our 15000 watt pure sine wave ac coupled inverter is also a DC to AC battery charger & transfer switch.
