Charger Settings in Stacked Configuration
The
$XWR3RZHU
includes a maximum 150A charger.
When using two stacked
$XWR3RZHU
inverter/chargers
connected to the
same battery bank,
a total of 300A
(150A
[
2) of bulk charging is possible into that single
common battery bank. For small battery banks and/or certain
battery types this bulk mode current may be too high,
therefore
$XWR3RZHU
models include a battery bank capacity
(
%DWW&DSDFLW\
)
setting and a maximum charge rate (%)
(
0D[&KJ5DWH
) setting.
The battery bank capacity (
&
) is the bank’s total Amp-hour
capacity, which is best determined by a qualified electrical
technician.
The
0D[&KJ5DWH
depends on the battery manufacturer's
maximum charge rate for the specific battery model being
used to construct the bank. This total bank maximum charge
rate is best determined by a qualified electrical technician.
Suitable battery types include Flooded, GEL and AGM.
For a Flooded type battery bank, the
SUHIHUUHG
charge rate (in
Amps) is usually 10-15% of
&
where
&
= battery bank’s total
Amp-hour capacity. However, the industry-accepted
PD[LPXP
charge rate is 25% of
&
. Some AGM or Gel battery
models may have a
PD[LPXP
charge rate as high as 50% of
&
and in rare cases, up to 100% of
&
.
EXPLOSION HAZARD
Do not mix different battery types within the same battery bank.
Failure to follow these instructions will result in death or serious injury.
RISK OF SHORTENED BATTERY LIFE
Do not exceed the battery manufacturer’s recommended maximum charge
specifications because the resulting battery temperature rise shortens
battery life.
Failure to follow these instructions can damage the unit and/or damage
other equipment.
