Configuration

Max Chg Rate
Full name Maximum charge rate
Configurable setting The actual battery charge rate is determined by two things. First, the MS2000 uses
the house battery Batt Size setting (C) on page 3–15 divided by 5 (C÷5) to
determine that maximum total charger output. This value is then modified by the
charge rate setting.
For example, if the house battery bank size is set to 300 Ah and the charge rate
was set at 100%, the calculation would be: 300 ÷
5 or 60 amps × 100% which is a
60 amp charge rate. If the charge rate is adjusted to 50%, the resulting charge rate
would be 30 amps (60 amps × 50%) total.
Even though you can set a house battery bank size of 2000 Ah, where C÷5 is 400
amps, the MS2000 would still charge at 100 amp, the maximum total charge rate.
When to use Displayed only if in charger mode when you wish to control the maximum charge
rate to your batteries.
Echo Chg
Configurable setting This setting lets you enable or disable the Echo Charger function.
When to use The MS2000 has a maximum total charge rate of 100 amps, split between the
main charger and the Echo Charger. The Echo Charger uses a maximum of 10
amps DC, which is not affected by the Max Chg Rate setting.
When the Echo Charger is enabled, 10 amps of the 100 amp charge output could
be delivered to the engine battery and 90 amps could be delivered to the house
battery bank. You must disable the Echo Charger if you want 100 amps of charge
current going to the house battery bank.
For example, if the bank size is 500 Ah or more and the Max Chg Rate is set to
100%, the calculation would be: 500 ÷
5 or 100 amps × 100%. The total output
would be 100 amps with 90 amps going to the house battery bank and 10 amps to
the engine battery.
