before I buy the device, I have one question. I don’t understand fully the Charge Only mode. If I set the device to Charge Only mode, will it output the power on AC out port, when there is a power on AC in? And if the power on AC in is lost, will it stop providing power to AC out port?
What I want to achieve is to automatically disconnect the devices that are connected to AC out port when AC in power is lost (I don’t want to use the device as UPS, just as battery charger and to protect the devices on AC out port).
In charger only mode, AC power flows from the AC input to the AC output. If AC input goes away the AC output would not be powered.
When the AC input is active, there is a direct connection between the AC input and AC output. So the amount of protection to the loads is minimal. Any AC input voltage or frequency variations pass to the loads. There may be some minor filtering or surge protection inside the Multi as well.
The Multi is a pretty expensive battery charger so if that’s all you need, there are other options. The right fit depends on how much charging power you need.
thank you for your answer. Does that mean that if we use “On” (over inverter) the 220V devices will be protected in the same way as if we would use a standard UPS device?
Also is it possible to somehow automatically change the mode to “Charger only” when the power is lost from the grid?
We don’t want to power our 220V devices when there is no electricity from the grid, and also to power it back when the grid power returns.
