Power equipment
We provide a full design and supply service, from initial customer requirements, through to supply of complete or partial solar or hybrid systems.
Complete MastMinder power systems
What's included?
Our systems can include all, or any of the following components as required:
PV panels
PV modules
Array structure
Rectifier modules
Batteries
Circuit breakers
All cables
Every nut and bolt to complete the job
Simulation report of expected results
Detailed installation guide
Remote installation support
The completed site can then optionally be remotely monitored by our monitoring system
System features
Fully integrated
All solar PV MPPT Modules, Grid/Generator rectifiers and optional Inverters are fully integrated into one complete system.
Standard Telecom grounding
All solar PV MPPT Modules, Grid/Generator rectifiers and optional Inverters are +ve grounded for standard telecom -48 volt load infrastructure.
Prevents lightning damage
Each solar string has a dedicated SPD and 50 Amp Solar module. If any lightning damage does occur, it's most likely to damage just one string or solar module.
Hot swappable
The solar modules and rectifier modules are all “hot swap” units allowing for rapid onsite replacement by non-technical personnel.
Configuration options
The configuration of the MastMinder solar power telecom supply system is shown below.
Module options
These MastMinder modules are designed to operate as an integral component in telecommunications power systems.
Solar controller high and low voltage versions
- Solar input range (100VDC - 400VDC)
- Design of power switch and output integration simplify operation assembly.
- Maximum Power Point Tracking (MPPT)
- Low input voltage: 58~150VDC
Rectifier module
The MastMinder rectifier module provides up to 3000 watts of power with 53.5V nomimal output.
It has a universal AC input range (90VAC~300VAC).
Module features
Extremely flexible
Can be applied as a stand-alone module
1U industrial design
Can provide up to 3000 Watts of power
High efficiency > 96%
Operating temperature range -40°C to +75°C
Active load sharing
Advanced internal monitoring
Applications
- Telecommunications
- Broadband
- Broadcasting
- Enterprise
- Railway
Inverter
The MastMinder inverter features a 19-inch rack-mounted design, with DC input reverse protection, DC input buffer protection, DC over/under voltage, overload, short circuit, over-temperature and other protection functions.
The kernel uses a microcomputer processing simple, reliable operation and rapid response.
PWM + SPWM pulse width adjustment output sine wave. The LCD display, can show the alarm, alarm records and so on.
Monitoring module
The compact MastMinder monitoring unit mainly detects the operation status of different types of power supply systems and controls their operation. It provides a rich interfaces which can be used to manage the site environment and alarm reporting. Interfaces include:
- sensor interface
- CAN interface
- RS485 interface
- input/output dry contact interface
The monitoring module also provides remote communication with third-party network management that supports the power total protocol, which enables remote power management.
