3.0 Setup
Info: If you are supplying two AC sources (utility and generator) to
the inverter's single input through an AC transfer switch, adjust the
AC Input Amps setting to the smaller AC circuit breaker size of the
two AC sources.
Info: The AC Input Amps setting is dependent on the stability of the
AC source. If using a generator, factors such as altitude and output
voltage regulation may require a lower setting than the generator's
circuit breaker size. For best performance, lower the AC Input Amps
setting to 1/3 of the generator's rated capacity, and then while the
generator is heavily loaded, gradually increase the setting as high
as possible, but ensure the voltage level stays above the 03D VAC
Dropout setting.
CAUTION: Unless you have an MS Hybrid Series inverter/charger—
which provides the Load Support feature—the AC Input Amps setting
does not limit the current to the inverter loads. If the current from
the loads on the output of the inverter are greater than the circuit
breaker rating on the incoming AC source, you may experience
nuisance tripping on this breaker.
• 03B Battery Type – Used to select the battery type, which determines
the battery charge profi le and ensures the batteries are receiving the
proper charge voltage. The fi xed voltage selections are GEL (for Gel
batteries), Flooded (for liquid lead acid batteries), AGM 1 (for Lifeline
AGM batteries), and AGM 2 (for East Penn/Deka/Discover/Trojan
AGM batteries).
Equalization charge voltage settings to be individually adjusted.
Table 3-2 to determine the specifi c charge voltage based on the battery
type selected.
Default setting: Battery Type = Flooded
Range: GEL, Flooded, AGM1, AGM2, Custom
Info: The voltage settings shown in Table 3-2 are based on the Bat-
tery Temperature Sensor (BTS) at a temperature of 77° F (25° C), or
not connected. If the BTS is connected, the actual charge voltage will
increase if the temperature around the BTS is below 77° F (25° C), and
decrease if higher than 77° F (25° C). This ensures the batteries re-
ceive the correct charge voltage regardless of temperature.
• 03C Max Charge Rate – Sets the maximum charge rate allowed
to charge the batteries during Bulk, Absorption, Float, and Equalize
charging. Selections are Max Charge = 0% up to 100%. The Max Charge
= 0% setting is available to help minimize charging while continuing
to allow pass-thru power. The rest of the selections are provided to
limit the charge rate to the battery bank, which helps prevent battery
overheating caused by charging at too high a charge rate.
The Max Charge Rate selections are provided as a percentage of the
inverter/charger's maximum charging capability. Refer to the label on
the side of the inverter (or owner's manual) to determine the inverter's
maximum charge rate. Once you fi nd this max charge rate, determine
the percentage needed to limit the charge rate to your battery bank.
Default setting: Max Charge = 100%
Range: 0-100%
