System Information

Overview

This page shows the current system configuration, power limits, data pipeline, and supporting components used in your solar dashboard environment. It is intended as a quick reference and a status explanation for how your FranklinWH system, solar arrays, Pi appliance, and dashboard all work together.

Components

FranklinWH aGate / Inverter – live power flows, SOC
A-Power Battery – 13.6 kWh usable capacity
Solar Arrays – South (7.6 kW) + West (2.8 kW)
Raspberry Pi 4 Model B – runs the Solar House bridge and publishes live metrics
Solar Dashboard – Pi-hosted real-time pages on local area network
History Logging – JSONL daily history snapshots
Replay Engine – smooth playback of historical days
TRMNL Display – external dashboard via screenshot page
Web Server – public pages at bbbrown.com

Data Files

Key files generated on the Pi:

solar.json – latest real-time snapshot
daily_summary.json – daily totals
history/YYYY-MM-DD.jsonl – per-day time series
solar_screenshot.png – TRMNL snapshot

Update Cycle

A Raspberry Pi fetches live data every few seconds, updates the local dashboard instantly, and uploads selected files to the web server on a predictable schedule. A TRMNL page is updated every 10–15 minutes to stay within the E-Ink device’s refresh limits.

Replay Page Notes

The Replay view reads from the daily JSONL files to provide a smooth, controlled playback of any day’s operation. You can scrub through time with the slider, change playback speed, or loop the entire day. The headline displays a concise summary: S x.x · H x.x · G x.x · B x.x · SOC xx%.
