Getting Started2.0

2.1 Overview

Thank you for selecting the TriStar MPPT 150V solar charge controller with TrakStar

MPPT

Technology. The TriStar MPPT 150V (TS-MPPT) is an advanced maximum power point tracking

solarbatterycharger.Thecontrollerfeaturesasmarttrackingalgorithmthatndsandmaintains

operation at the solar array peak power point, maximizing energy harvest.

The TriStar MPPT 150V battery charging process has been optimized for long battery life and

improved system performance. Self-diagnostics and electronic error protections prevent damage

when installation mistakes or system faults occur. The controller also features eight (8) adjustable

settings switches, several communication ports, and terminals for remote battery temperature

and voltage measurement.

Please take the time to read this operator’s manual and become familiar with the controller. This

will help you make full use of the many advantages the TriStar MPPT 150V can provide for your

PV system.

2.2 Versions and Ratings

There are three versions of TriStar MPPT 150V controller:

TriStar-MPPT-30

• maximum 30 amps continuous battery current

• 12, 24, 36, and 48 Volt dc systems

• maximum 150 Volt dc solar input voltage

• RS-232 and MeterBus

communication ports

TriStar-MPPT-45

• maximum 45 amps continuous battery current

• 12, 24, 36, and 48 Volt dc systems

• maximum 150 Volt dc solar input voltage

• RS-232 and MeterBus

communication ports

TriStar-MPPT-60

• maximum 60 amps continuous battery current

• 12, 24, 36, and 48 Volt dc systems

• maximum 150 Volt dc solar input voltage

• RS-232, EIA-485, MeterBus

, and Ethernet communication ports

To comply with the National Electric Code (NEC), the current rating of the controller must be

equal to or greater than 125% of the solar array’s short circuit current output (Isc). Therefore, the

maximum allowable solar array input to the TriStar MPPT 150V controller for compliance with the

NEC is:

TS-MPPT-30: 24 amps Isc*

TS-MPPT-45: 36 amps Isc*

TS-MPPT-60: 48 amps Isc*

*Solar array Isc @ STC
