Customers have been a fan of our 'Ultimate Dual Battery setup' for years now as it enables all the benefits of charging through a BCDC and the safety and convenience of an added jumpstart feature. Addionally, Solar could be added on BCDC1225(-LV) and BCDC1240(LV) installations with the 'BCDC with 12V and Solar Inputs and Jump Start Feature' diagram.
With our Dual Input BCDC range, the setup is even easier! As per the diagram below, a SBI12 can be used and no relays are required.
