Energy Logger Rental Service – Load Profile Measurement, Power Quality and Peak Demand Analysis
R 2 900.00
Rent a professional energy logger to measure load profile, power quality, and peak demand at your site. The service includes a one-week measurement period, raw data, and a finished analysis report — useful for project planning, energy efficiency audits, sizing solar and backup power systems, and verifying electricity bills.
- Rental per week: R 2900 (Rental fee, paid online at checkout.)
- Refundable deposit: R 7000 (Automatically added to cart. Fully refunded when the logger is returned in working condition.)
The “Energy logging service” includes the following:
- Professional energy logger rental for one week
- Free shipping in Germany and South Africa, flat rate elsewhere in Europe
- Raw measurement data in .csv format
- Meter data analysis and visualisation report in Excel
- Technical support by phone and email
Available on request:
- On-site installation and removal by a qualified electrician
How the rental service works
The process goes as follows:
Energy logging for planning and project approval
Before installing new charge points, heat pumps, or PV system extensions, you need to know how much electrical capacity is actually available at your site — and your grid operator may also require a formal load profile before approving the project. Either way, accurate measurement is the foundation: it tells you what’s possible, and it gives the grid operator what they need.
We supply customers across Europe and South Africa with:
Energy logging for energy efficiency
Energy logging is the foundation of any serious efficiency programme. You can’t reduce what you don’t measure. Renting a logger gives you the data to identify exactly where, when, and how much energy is being wasted — without committing to the cost of buying equipment outright.
What you can do with the data:
Energy logging for backup power and renewable energy
Before installing solar, batteries, or backup power, you need accurate data on what you actually consume. Renting a logger for one week gives you the load profile needed to size the system correctly — avoiding both undersized installations that fail under load and oversized systems that waste capital.
What the data tells you:
Energy logging for verification of electricity bills
If you suspect your electricity bill doesn’t match your actual consumption, energy logging gives you the proof. A one-week measurement is often enough to identify metering errors, incorrect tariff classifications, or peak demand charges that don’t reflect real usage.

Identify energy savings with our power and energy logger rental service
Electrical power usage is changing constantly. This means loads on the electricity network are changing, resulting in energy waste. Discovering the source of this waste enables you to develop strategies to reduce the waste. With three-phase power and energy loggers, you can find out where and when you are consuming power and put actions in place that ensure you’re using your energy efficiently. By continuously visually presenting power and energy usage, we can help you quickly and easily identify savings opportunities, providing a rapid return on your investment.
Power and energy logging explained
When a piece of equipment is operated, it instantaneously consumes a specific amount of power in watts (W) or kilowatts (kW). This power is accumulated over the operating time and expressed as energy consumed in kilowatt hours (kWh). Energy is what your electric utility charges for; there will be a standard charge from the utility per kilowatt hour. Utilities may have other additional charges, such as peak demand, which is the maximum power demand over a defined period of time, often 15 or 30 minutes.
There may also be power factor charges, which are based on the effects of the inductive or capacitive loads in the facility. Optimising peak demand and power factor often results in lower monthly electricity bills. The GES ME435 Three Phase Electrical Energy loggers have the capability to measure and characterise these effects, enabling you to analyse the results and save money.
