Enhanced functionality for world-class energy management


The adjustable feed-in reduction (x %) is now a standard function and there is a free choice of Solar-Log WEB Enerest™ portals. Depending on the particular energy management needs, customers can simply choose between the version M, L or XL portal. Depending on the version, Solar-Log WEB Enerest™ offers reporting and analysis tools for the efficient use and monitoring of PV energy.

Simple feed-in management with fixed power reductions (x %)

Many plant operators have to carry out a fixed feed-in power reduction or even complete reduction of 0% feed-in power. With the Solar-Log 50, the amount of feed-in power can easily be set to the desired percentage. The remaining PV energy is consumed locally to prevent any valuable PV energy from being wasted.

Battery storage monitoring – record and save power surpluses

The energy produced above the set percentage, for example, can be stored for later consumption. That is why the Gateway Solar-Log 50 monitoring is not just limited to the PV plant itself, but also includes additional components such as battery storage. The integration of the battery storage system allows the current charge level to be displayed directly in the portal. As a helpful analysis option, the charge history is displayed for the last seven days. The electricity savings from using the battery and the efficiency of the battery solution itself are also displayed. The user sees energy usage from the battery and the savings gained by using this stored power.

Fault and yield notifications directly per e-mail

The PV plant’s yields are quickly recorded and communicated by sending e-mail notifications. This option is available with all of the Solar-Log WEB Enerest™ portal versions. The XL version also provides the option to send PV plant fault notifications per e-mail.

Easy to install and flexible upgrades

Thanks to the top-hat-rail mounting, it is quick and easy to install the Solar‑Log 50. Since time is money, the plant operator saves again and does not need any additional space for a monitoring system. Various licenses are available for Solar-Log 50 add-on functions. For example, there is a license to increase the installed power output to 30 kWp.
