Morningstar 150V dc 45A Solar Charge Controller

Morningstar TriStar MPPT solar controller is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 3 kW.
The controller provides the industry highest peak efficiency of 99% and less power loss compared to other MPPT controllers.
The TriStar MPPT features a smart tracking algorithm that maximises the energy harvest from the PV by rapidly finding the solar array peak power point.
Includes on-board Ethernet for a fully web-enabled interface and up to 200 days of data logging
