TriStar MPPT & MeterHub in GridTie System

The Slovak Republic:
Remote ‘Modern’ Home … Grid-Tied w/Battery Back-up Installation
The Challenge:
• Provide stable and reliable back-up solar-electric power to this
modern home in the Slovak Republic.
The System:
• 3kWp Back-up PV System
The Solution:
• 3 TriStar MPPT™ 60A Charge Controllers
• 1 TriStar™ Remote Digital Meter
• 1 MeterHub™ MeterBus Communications Hub
• Why?
– Increased Energy Harvest, Long Operating Life & High
Reliability.
• The TriStar MPPT Controllers have an earlier turn-on time &
significantly better efficiency at lower output levels.
• The TriStar MPPT Controllers keep the batteries at a higher
State of Charge (SoC) for the same PV array. Higher SoC means
better battery health & longer battery bank life. It also means
more time before a Low Voltage Disconnect, which equates to
better autonomy for the system.
