Product Description PLEASE NOTE – BBR works best with brand new models in stock now (June 2022 onwards). If you have a BB1240/70/120 from before this date, you may have to send the BB back to Sterling Power to use for latest firmware. As this is a new item, it has features that require BB firmware modifications. The default current setting for the BB range is 100% – meaning that the performance default is full power. If you wish to reduce the performance of the BB, here you can set to 85% or 65% charge rate. Examples of why you may wish to reduce performance: 1) if you have solar panels and the weather is good, by reducing the power of the BB, you shall conserve fuel. 2) The alternator is better suited running at slightly lower current than what was expected. 3) It may be recommended by your battery supplier to charge the battery up at a slightly lower current. If one of your lithium batteries within your leisure battery bank fails, you may be exceeding the C rating of the remaining batteries. 4) future proofing. If you have installed a high powered BB, in the assumption that one day you shall put a larger alternator on and/or more batteries in your system. You can reduce the power for the immediate install and increase the performance of the unit at a later date.
