Per second metric accuracy

Real-time metrics makes all the difference and gives true insight into how your system performs. Instant updates are really convenient if your trying different settings to see how it affects your system.

10+ Years of historical data via interactive charts

SolarAssistant puts you in control of your data by storing it on your device instead of a cloud service. You can store 10+ years of data on the default 16GB SD card.

Modern, efficient interface

If you are currently using a platform such as VNC or AnyDesk to access your monitoring software then you are effectively streaming video just to use an application. It just doesn't make sense. We built our entire platform from the ground up with the latest technology.

Remote monitoring and control

Mecer remote access

Web, Android and iPhone

Remotely monitor and administer your site via web or our mobile app. All functionality is available via web and mobile as we use our own app. We do not use Emoncms.

Multi-site access with a single login

Via the SolarAssistant platform you can get a list of all your sites and access them with a single login. A must have for solar installers.

User administration

You can invite new users to your sites which will send them a welcome email that prompts them to set a password. Password resets are self-service via email.

Parallel support

Via a single cable, SolarAssistant can read all parallel connected inverters. Some metrics such as inverter temperature, bus voltage and MPPT2 (Mecer Max only) can only be read from the inverter that is directly connected. If you want to read these metrics from all inverters, then connect each inverter via it's own USB cable.

Direct BMS (battery management system) connection

Why would you want to connect your BMS to SolarAssistant?

Only the latest Mecer inverters can read the battery state of charge from the battery directly. If you have one of these inverters, SolarAssistant will read the battery state of charge directly from the inverter.

In all other cases, you want SolarAssistant to read data directly from the battery via a dedicated USB to RS232/RS485 cable to enable:

  • Accurate reporting of the battery state of charge, temperature, capacity, cell voltages, etc.
  • Power management based on the true battery state of charge.
