I have six 100 watt solar panels on the roof of my off-grid cabin. I have been using lead-acid batteries with an 80A PWM charge controller. Charge voltage had been set at 13.8V. I want to swap out the lead-acid batteries for a 300AH LiFePO4 battery. I reset the charge voltage to 14.4V. I have a 12V timer that turns on a 600W sine wave inverter which powers four web cams and a router for five minutes every hour. That 600W inverter was OK being fed 13.8V but it doesn't like 14.4V or even 14.2V. It'll work with 14V but I suspect I won't get best LiFePO4 charging efficiency using 14V instead of 14.4V or even 14.6V. What's the solution? The 600W inverter, cameras, & router are on a separate 12V line. Is there some kind of step down voltage regulator I can buy? Is there an inverter that isn't so fussy about being fed 14.4V? Thanks!
