Operating Instructions for Solar Charge Regulator LRM 1218
For example, five solar modules each rated at 55 Wp can be connected in
parallel:
Per solar module e.g.
Total nominal current
Battery type Charging-
set voltage
Supply mode Fixed voltage 13.4 V
AGM2 14.7 V
Lead-gel/ 14.4 V
AGM1
Lead-acid 14.4 V
The temperature correction of end-of-charge voltages is --20 mV per degree
of temperature increase (in relation to 25 C) or +20 mV per degree of tem-
perature reduction (voltage limits: U
limit at 14.9 V is in consideration of the maximum input voltage of the consu-
mers connected).
Schaudt electroblocks with SDTBUS (they have a separate input for
F
the solar currents of leisure and starter batteries, and a connector for
the SDTBUS)
Schaudt electroblocks with a separate connector for the solar currents
F
of leisure and starter batteries; possibly also a connection for current
display (relayed to the DT .../LT ... control panel connected to the EBL
...)
Schaudt electroblocks with a retrofit adapter for charging the starter
F
battery
Direct connection to leisure and starter batteries for external systems;
F
solar current display by LT 320 (available optionally) possible
