Solar-Log: cost, fit and limits
Solar-Log is a monitoring product line from Solar-Log GmbH in Germany that combines data loggers with web portals for solar plants, offering remote configuration, a live view of system parameters and a plant monitoring service.
What to know first
Solar-Log's page describes monitoring that shows all relevant system parameters at a glance, remote configuration that saves on-site deployments and plant monitoring that can be booked as a support service. The system can be extended with Solar-Log WEB Enerest and Solar-Log WEB-4U. A shop link exists, but no prices or plans are published, and no AI feature is named. ISO 9001, 14001 and 27001 badges appear.

What Solar-Log does
- System overview
- All relevant system parameters are available at a glance at all times, per the page. Which parameters are included depends on the devices connected to the logger.
- Remote configuration
- Remote configuration options are described as saving on-site deployments. The page does not list which settings can be changed remotely or who may do it.
- Plant monitoring service
- Plant monitoring can be booked as a service for support. The page gives no price, response time or scope, so the offer needs a written description.
- Extendable system
- The system is described as flexibly expandable with Solar-Log WEB Enerest and Solar-Log WEB-4U. The page does not explain what each adds, so an installer should ask for a comparison.
How Solar-Log handles your data
The page shows ISO 9001, ISO 14001 and ISO 27001 badges that link to certificate PDFs, and it refers to a security subdomain. The page we read does not state where monitoring data is hosted, how long it is retained or whether customer data trains AI models. Ask Solar-Log for its privacy policy and the scope of the ISO 27001 certificate before connecting a plant, because the vendor's policy was not checked for this.
Where Solar-Log falls short in practice
- No plans or prices. Only a shop link is shown, so the cost of the portals and the monitoring service cannot be read from the page. The cost of the portals and of the monitoring service must be asked for separately.
- No AI feature. The page names no AI, so buyers who compare portals on AI functions will find nothing to assess here. Buyers who compare portals on AI functions will find nothing to assess or to test here.
- Detail pages not shown. Several products are named without description, and a privacy text did not appear on the page we read, so the facts stay thin. Several products are named without a description, so some facts are missing from the page we read.
Alternatives to Solar-Log
Solar-Log: common questions
What does Solar-Log monitor?
The page says all relevant system parameters are available at a glance at all times. Which values appear depends on the connected devices, and the page does not list them. Ask Solar-Log for the compatibility list for your inverters and meters before you buy a logger.
Can Solar-Log be configured remotely?
Yes, the page describes remote configuration options that save on-site deployments. It does not say which settings are reachable remotely or what access control applies. An installer should ask for the list of remote functions and how customers grant access.
Does Solar-Log offer a monitoring service?
The page says plant monitoring can be booked as a service for support. It does not state a price, response times or what the service covers. Request a written service description and compare it with the cost of watching alerts in-house.
Which certifications does Solar-Log show?
The page shows ISO 9001, ISO 14001 and ISO 27001 badges linking to certificate PDFs. The certificate scope was not read for this page, so confirm that the portal and data handling sit inside the ISO 27001 scope before you rely on it in a security review.
What are Solar-Log WEB Enerest and WEB-4U?
The page names them as ways the system can be flexibly expanded. It does not describe what either one does. Ask Solar-Log for a feature comparison and prices before choosing, because the page we read does not allow a comparison.
