Two Modes: Pass-Through Mode and Normal Mode
PASS-THROUGH MODE: When the L-1500 is connected to an AC and/or DC source and is still powering another device through the output, the power is passed directly to the device being powered. Using the regular 120V AC input, such as from a wall outlet, the L-1500 allows a maximum of 15A input on the AC side. While in Pass-Through Mode, the display scree will read PA:SS.
NORMAL MODE: The maximum AC input while in normal mode is 12A. The output to the battery from the L-1500 circuitry is charging at 25A at 14.6V. Regardless of how much current is connected, it is safety-limited to 25A total input to the battery from all inputs. The display screen will show a flashing battery symbol showing the percentage charged, as well as the charge time, until it reaches 00:01. At this point, the unit may take up to 20 minutes to balance the charge of the cells for optimal battery performance and overall life. When the unit is completely finishes the charging cycle, the display screen will read FU:LL.
High Output USB: The L-1500 comes equipped with 4 USB ports. Each port can carry a maximum of 3A at 5V DC, but the combined amperage of the 4 USB ports cannot exceed 8A. The USB ports will self-regulate to evenly provide the devices connected with the highest healthy charge possible.
Anderson Power Poles: The L-1500 is equipped with versatile Anderson Power Pole inputs. A maximum of 20A can pass through the Anderson Power Pole outputs. Homemade or non-standard Anderson Power Pole devices will void the warranty.
Cigarette Adapter: At a maximum of 10A, the L-1500 can power many DC 12V devices commonly used in cars with the Cigarette Lighter Adapter. The 10A limit can be combined with Anderson Power Pole limit of 20A, giving a total of 30A of DC output.
The L-1500 will accept voltages from 12V to 50V at a total of no more than 15A. The L-1500 may be charged with AC input and DC input at the same time with a total of 40A going into the battery. The charge time is estimated at about 2 hours. The L-1500 is equipped with a safety fuse that will cut off any voltage that exceeds the DC 50V limit and will reset once the voltage is within the 12V-50V range. Windmills, solar panels and kinetic energy converters are all excellent DC input sources, provided the voltage range is maintained.
The L-1500 will output 1500W continuously for roughly 15 minutes. The AC output has been limited to 15A. As an added safety feature, the L-1500 AC output will run at 1599W for 5 seconds before decreasing the output to 1500W. Wheat grinders and washing machines require a higher peak for several milliseconds while the device regulates to its operating wattage within the 1500W range. The L-1500 also governs the power output to protect against internal heat build-up that may harm the components and battery.
