MeterHub

MeterHub

The MeterHub™ allows up to 15 Morningstar products on a single MeterBus network. The product electrically isolates devices that supply power to the network, preventing damage to the network in the event of grounding problems. Five status LED’s indicate the proper network connection to each port. In multi-controller systems the TS-M-2, TS-M-2-600V and TS-RM-2 are networkable using Morningstar’s MeterHub to allow individual controller data and aggregate system data to be displayed together on a single meter. Thus, for example, multiple controllers can share a TriStar Meter or Relay Driver. The MeterHub is suitable for either wall or DIN rail mounting and it is compatible with:
  • TriStar MPPT 600V Controller
  • TriStar MPPT Controller
  • ProStar MPPT Controller
  • SunSaver MPPT Controller
  • TriStar Controller
  • TriStar Meter 2
  • TriStar Remote Meter 2
  • Relay Driver

Key features and benefits

  • Fanless design for long-term reliability–no moving parts to fail, no dirt and debris sucked into the controller, and no parasitic load to reduce efficiency.
A. Premium high-frequency CoilCraft surface mount inductors

They’re worth it, because they provide the faster power “tracking” that lets us engineer this much power and control into a compact design.

B. High-frequency design

Combined with premium, “over-spec’d” components, this greatly improves control response which guards against system transients, regulation overshoot and overcurrent/overload conditions

C. Built-in 4500W Transient Voltage Surge Suppression for lightning protection

Nature do your worst–this controller can take it

D. Large diameter, high torque, corrosion resistant terminals

If you’ve ever trashed a lesser terminal during an installation, you’ll appreciate some “overkill” here

E. DirectFET™ MOSFET power devices

Allows the surface-mounting of critical components underneath the main board next to the heat sink, which reduces heat travel distance and keeps the controller even cooler

F. Highly-conductive aluminum heatsink extrusion

As opposed to cast aluminum, which is less effective in passive cooling applications

G. Communications/data port with serial/meter auto detect

“Talks solar” with standard industry language, for system monitoring and cloud connectivity-speaks Modbus, and SNMP (with the EMC-1)

H. Lithium foldback circuit

Lithium batteries are expensive and vulnerable to cold temperatures. When it gets close to freezing, the controller backs-off charging to avoid damaging batteries

I. High-speed ARM processor

All-digital calibration for high accuracy, using the same efficient technology found in advanced mobile device

J. TrakStar™ Technology

Morningstar’s hallmark MPPT technology precisely seeks and locks onto the true maximum power point quickly and accurately, to ensure the highest output possible from a solar array

K. Large format, high-resolution backlit LCD

When you’ve been in the field installing, you appreciated being able to read a crisp, high contrast display on site

L. 5 year warranty

Up to 2 1/2 times longer than some competitors in this class

M. Self-diagnostics

ProStar is smart enough to monitor and analyze system performance, and alert you when you need to know

N. High temperature architecture

Heat is the enemy of all electronics. That’s why Prostar’s critical components are rated to withstand temperatures right up to the boiling point of water (100°C)

O. Lexan polycarbonate UL listed case

Protects the precision electronics inside with an impact strength 30 times greater than the acrylic thermoplastics commonly found on lesser controllers

P. Cooling Fan

Just kidding. We’ve never needed them

System Diagrams

    Off-Grid Diagram with DC Load

The schematic diagram above, illustrates how the ProStar MPPT regulates power to batteries and a direct current (DC) load in an off-grid system.

  1. Sunlight contacts the solar modules, which convert solar into DC electrical power that it delivers to a charge controller.
  2. The charge controller regulates the amperage and voltage that is delivered to the loads and any excess power is delivered to the battery system so the batteries maintain their state of charge without getting overcharged.
  3. During the evening when there is no sunlight, battery power is used to run the load.

 


 

    Off-Grid Diagram with AC Load


The schematic diagram above, illustrates how the ProStar MPPT regulates power to batteries and an alternating current (AC) load in an off-grid system.  This diagram is very similar to the DC load diagram above it except an inverter has been added.

  1. Sunlight contacts the solar modules, which convert solar into DC electrical power that it delivers to a charge controller.
  2. The charge controller regulates the amperage and voltage that is delivered to the battery system so the batteries maintain their state of charge without getting overcharged.
  3. Batteries deliver power to the inverter which converts DC to AC power that it delivers to the load.  Notice that  the inverter is connected to the battery, not the controller’s load terminals, like we did in the DC load example.  That’s because the inverter can have a high energy surge upon start up, and this high current surge might be higher than the rated capacity of the charge controller, whereas the batteries will be able to meet the high energy surge requirement.
