2 mesice stary, pro me nepouzitelny, protoze muj panel dava vetsi napeti. Svorky na jednu baterku 16A nebo na dve 8A, LED indikace + dokoupeny hlinikovy chladic. Input voltage: solar panels 15-22 V open circuit voltage, 12 V rated voltage Max. charging current: total 16 A (2 accumulators of max. 8 A each or 1 accumulator connected in parallel at both outputs up to 16 A) Connections: 1 or 2 accumulators 12 V. When connecting only 1 accumulator, it has to be connected at connection 2. Displays: one display per accumulator "accumulator is charging", 1 display: "all accumulators charged". Refrigeration: In case of currents more than 4 A the module has to be screwed with the metal bottom on a heat sink with a surface of more than 300 sq. cm. Fuse: A pre-fuse F16 A is necessary (not included) Switch-on voltage: accumulator approx. less than 13.4 V ± 5 % Switch-off voltage: „accumulator charged“ approx. 14.4 V ± 5 % Own current consumption (is taken from the accumulator): less than 2 mA Reverse current-proof (no additional diode required) Dimensions: approx. 87 x 60 x 32 mm
