Stoll Design

Your whole property on one screen.

Solar, battery, generator, propane, heat and breakers, read every minute. You hear about a low tank, a tripped breaker or a filter that’s due before it becomes a cold night.

Readings like these come in every minute. The numbers here are an example.

What it watches

It reads the equipment you already have through the apps it already talks to, so there is nothing to rewire. Each system gets its own page, and Home shows the lot at a glance.

Solar and battery

Every panel string and inverter, the battery’s charge, voltage and cell temperatures, and when it will be full at today’s sun and tomorrow’s forecast. It flags an array that falls behind the others.

Full by 1:40 p.m.Battery at 84% with 6.2 kW of sun

Generator

Each run: when it started, how long it ran, what it made and roughly how much propane it burned. Oil changes come due by running hours, the way the manual counts them.

148 h to the next oil change52 of 200 h since the last one

Propane

Tank level from your tank monitor, how fast you’re using it, how many days are left and what is burning it: furnace, generator or both.

About 31 days left62%, using 9.6 lb a day

Heating and cooling

Thermostats and mini-splits room by room, with set points you can change from your phone, and running hours for every head and outdoor unit.

Office 21.0°Heating to 21.5°

Breakers

Live power on every smart breaker, what is drawing the most right now, and a warning the moment one trips.

Shop outlets tripped3:12 p.m.

Maintenance

Filters, oil and anything else you add, each on its own window of running hours or months. Log the work for one unit or several at once and the clock restarts.

Built on a working off-grid home

The monitor runs every day at our own property in rural Ontario, where the power has to work through a Canadian winter. Every alert in it exists because something needed watching there first.

  • 56solar panels on six arrays, across two inverters
  • 5battery packs in one bank
  • 1propane generator for the dark weeks, and a propane furnace
  • 4mini-splits, in-floor heat, and a panel of smart breakers

Getting started

We set it up with you. You keep your equipment and its own apps; the monitor reads from them.

  1. Tell us what you have

    Inverters, batteries, thermostats, mini-splits, tank monitor, breakers. A short call is usually enough.

  2. We connect it

    Your own private address, such as yourname.stoll.cc, set up with your equipment’s sign-ins and nobody else’s data.

  3. Open it anywhere

    On your phone or computer. Set the maintenance windows you want and it lets you know when something needs you.

Everyone sees it. Few can change it.

Share it with the family without handing over the power system.

Viewing

Anyone you give the link to sees every reading and alert. Nothing can be changed.

Household PIN

Change temperatures and log maintenance. It locks again ten minutes after the last change.

Owner sign-in

Inverter settings and breakers need the full sign-in, and every change is written to a log.
