Need to run L1 Pro 32 with S2 sub on battery power. Saw YouTube where owner used Expert Power 400 to run system. Have two marine deep cycle batteries; one lead-acid at 76 Ah, and second battery is LiFePo4 at 50Ah. See no reason why coupling either of these batteries with a pure sine wave inverter (minimum 500W with 1kW surge, or just a 1kW inverter) wouldn't work, but looking for input so I don't inadvertently do something really stupid... dB SPL would RARELY exceed 100 -- 110 worst case. Thoughts?
Hey UberGoober and welcome to the Pro-Portable Community! I was able to get some insight with the Bose Engineering Team who provided the following response:
Although we test our products on inverters for major audio artifacts, we don’t recommend that customers use inverters as there are few variables that could negatively impact the systems performance.
Based on the setup described, the most likely negative outcomes are that the inverter will shut down from overload or that there will be some audio artifacts, however, a pure sine wave inverter is a good choice and it’s unlikely that you would experience any major artifacts. Running the Pro32 and Sub2 together, at maximum continuous output, the inverter will need to supply 600-800W continuously, and thus the battery will last about 45
minutes. You would have to use a higher-output inverter, but given the SPL described and, likely, the Pro32/Sub2 won’t draw that much power, so the inverter should be able to run and the battery could last more than an hour.
