List out restrictions
- Can the battery monitor be installed inside the battery room?
- Can the BMS be connected to your business network?
Communication, NOC and SCADA
- Is the Ethernet available?
- If no Ethernet, is there a dry contact input?
- Are you considering a 3G/4G plan? ($15 per month, plus a gateway $250)
- What is the preferred protocol: Modbus-TCP (Ethernet) or Modbus-RTU (Serial)?
PREPARE RFP/RFQ
- Obtain a reference RFP/RFQ from BatteryDAQ (we have worked on 100+ RFP/RFQs.) or other source as the starting point.
- Cost/benefit analysis for certain features. Cross some lines such as:
[Temperature monitoring for each cell/block in a string] One string can only have one current passing through, which is the only source to heat up individual battery, unless there is a shortage on a block, which can be detected by voltage instead of temperature.
[Wireless modular] Nightmare to maintain thousands of wireless modules.
TRIAL
- At least from 2 major vendors
- Comparison table [Consulting BatteryDAQ or another expert]
- Install by yourself or your technician to evaluation the installation difficulty and cost.
PILOT
- Different cabinets, rack layouts and battery configurations
- NOC or SCADA integration
- Train your own technician or contract to a 3rd party installer
FULL SCALE
- Total cost calculation (monitoring units, harness/cable, installation, software/data, any recurring fees)
- Data management and remote/cloud access, maintenance/subscription fees
- Alarm delivery to the NOC or control room
- Pricing and quantity order delivery time frame
- Stepped approach, or full scale deployment
- Payment terms
Keep in mind, a web conference with BatteryDAQ expert may save your time and money.
