This is a recent purchase due to a problem we had last year whilst travelling. I have a 40 Amp unit that hopefully I will not need to use much given the size of the battery and plenty of solar to charge it. I now have MS View on my laptop and a Cat 5 cable permanently connected to the regulator and routed to the bottom of a cupboard in the van should I need to make any changes. It also has settings that can reasonably be described as safety features that can be adjusted/enabled but understanding what they meant required me to contact Morningstar for answers, very helpful they were to. Making changes after connection is a follow the prompt process as long as you understand what all the settings are and what they need to be. Youtube came to the rescue and provided the missing information and I was able to make the necessary changes on the laptop so that they could see one another. Morningstar have online videos which walks through all the settings that are there but frustratingly, it does not tell you what you have to do to get the laptop to 'see' the regulator.Īs I found out, simply connecting the two with a Cat 5 cable is insufficient. I am told that some use the Gel setting as it is 'close' to what they want. You can select predetermined algorithms via dip switches inside the unit for the likes of lead acid, AGM and Gel with but Lithium requires re-programming if you want specific settings. However, like nearly all manufacturers, Morningstar regulators do not come with a charging algorithm for Lithium. These regulators would be familiar to many owners as Bushtracker use them, they are one of the better units you can buy. In theory this array generates 24 amps at up to 48v yet yet i am getting much more than that, the magic of MPPT.Ħ0 Amp Morningstar Tristar MPPT. When rolled out into the sun for the first time, string voltages were between 38-40v, with 56 amps showing on the regulator. Not necessary I know but allows me to monitor their pefomance. The string gauges and the C/B's are a nice to have as it allows me to read individual string voltages. The wiring from each string goes through a circuit breaker (C/B) in an overhead cupboard before paralleling on a busbar and going down to an array isolation switch in the load space. Panels are series wired in 3 strings comprising of 2 panels each. The supplier required a separate C/B and feed wire from each pack to the Battery Control Unit.Ĥx145W and 2x135W Kyocera panels. Had to do a small modification to the length of the space to give me working room and wriggle room to run cabling. I wanted packs that would fit in the same space, height wise as the existing AGM's and the 160 A/HR units fitted the bill. I will attach some photos of the completed system for those that are interested but beforehand I will give a description of the system I put together.ģx 160 A/HR Lithium packs from EV Power in WA. Thank you to all those who provided information when i was planning the transition from AGM to Lithium.
