The 825 Watt Solar kit is easy to install with only three panels to connect in parallel on an RV or Off Grid 12v-24v-48v system. This kit utilizes “oversizing” by using higher voltage panels. You can size Morningstar’s MPPT controllers well above the Maximum Nominal Solar PV Input rating without damaging the controller and without the charging current exceeding the maximum output rating.
Energy harvesting during lower power production periods (cloudy weather) is often more valued than during times when the array can operate at full power (sunny weather). These controllers can limit current and will run at 100% of rated output, and work especially well when your batteries are deeply discharged. Oversizing runs the controller at maximum levels more consistently
The controller was designed with this power-shaving capability and when oversized it does not void the warranty.

Morningstar’s TriStar MPPT solar controller with TrakStar Technology is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 3kW. The controller provides the industry’s highest peak efficiency of 99% and significantly less power loss compared to other MPPT controllers. The TriStar MPPT features a smart tracking algorithm that maximizes the energy harvest from the PV by rapidly finding the solar array peak power point with extremely fast sweeping of the entire I-V curve. This product is the first PV controller to include on-board Ethernet for a fully web-enabled interface and includes up to 200 days of data logging.

The meter will display a great deal of information about the TriStar controller and the operation of your system. In addition, the meter enables manual functions and controller diagnostics. These capabilities will increase your confidence that the system is working properly and will help you to improve system reliability, battery life, and system performance. It is worth the time getting to know your meter!
