MUST READ
For the majority of users, reading this paragraph should be sufficient for installation. The unit can be
installed by simply connecting it between an input and output battery, as depicted.
The solar panel’s
positive and negative connectors go to the +ve and -ve connectors (BBS1230 model only) - voltage should
not exceed 31V (12V panel).
The BB, by default, shall start charging when the starter input voltage exceeds
13.5V and switches off when the voltage drops below 13.3V (all models). The default charging profile is
14.4V abs. and 13.6V float -
for sealed lead acid batteries
(x2 for 24V | x3 for 36V | x4 for 48V).
This means that
the vast amount of installations can be fitted out of the box without any adjustments.
In certain
circumstances, when installing in a Euro 6 vehicle, we recommend using an ignition feed to the unit. When the
ignition is live, unit starts charging (may take up to 60 seconds). Please read the manual for additional information. If
in doubt, and installing on a New Euro 6+, use ignition feed. For info on BMS, remote sense, temp sensors and
remote control, please consult the manual. Solar charge shall operate when engine off and predominately go to the
leisure battery. There shall be a small 0.5A-1A back feed to the starting battery to keep it topped up, too. Maximum
wattage that can be harvested from the solar panels is 350W - 31V maximum and 16A maximum.
BBS1230 - New to 2020
Solar Panel up to 31V (nominal 12V rated) - do not exceed.
No limit to wattage, however, max harvest is ~350W
Negatives should all be common.
Use cable, do NOT use chassis.
