Title: XW/SW - Charge from generator while inverting?
Post by: Solar Islander on May 26, 2015, 01:31:02 AM
Thinking of buying either an SW or XW inverter, but not sure if I quite understand - from a previous thread it appears that most inverter chargers cannot supply / pass through AC while charging a battery.

Can the Schneider Conext SW or XW's supply AC to loads while charging from a generator?

Or is that why people buy Iota chargers etc. even though they own a perfectly good charger in their inverters? ::)

Thanks, Graham

All the major inverters (Outback, Schneider, SMA and Magnum etc) WILL pass the ac through anytime they are charging, this is automatic internally.

Thanks - That's pretty clear now! - Graham  :)

When there is AC present (grid or generator) the internal transfer switches connect the loads to the AC source.  And battery charging commences.  The inverter is Charging batteries, not inverting.

With the XW series, there is an additional mode (other hybrid inverters may have something like it too) called Generator Support, where if the inverter, with all it's sensors, determines that the loads are larger then the programmed size of the Generator, will cease charging, and sync with the generator, and provide power to the loads, so your 6Kw inverter can sync with the 5Kw generator and power a 10Kw load (for as long as the batteries hold out) when the load eases off, the inverter reverts back to charging.  It gets used in my system all the time, when the pumps kick in, or the deep freeze in the garage starts.
