I'm a bit confused by the behavior of my split-phase configured pair of LV-6548s. They are a couple years old and have only be put into service a few months ago, adding solar panels and battery capacity as I go. These units are used as off-grid in my home and have A/C grid available when solar or battery are not enough. First thing I've noticed is these units seem to be heat adverse since... I experienced 90-100 F degree temperatures in my garage this summer and they appear to de-rate themselves significantly as internal temps approach 70 C (as reported by Solar Assistant).
My latest odd behavior is related to large loads coming online.
Running in SBU mode, if solar is negligible at the time and battery is nearly 100%, a 4500 watt load switched on causes the inverters to immediately switch to grid bypass even though initially there was only a load of a few hundred watts. Batteries should have no problem delivering the power (two 14.5 kwh banks, each set for 120 amp discharge).
Anyone have any ideas what might be looked at? When solar is available, it seems to have no problem powering the load, even with battery assist. Do these inverters still deliver 6500 watts AC even if powered from battery only?
Thanks for anyone's help!
