1) Common breakdowns & what to maintain
- Micro-cuts & mains switch : laptop/box restarts, video calls cut off → UPS required.
- HS Internet Box (local/ISP outage): keep a 12V 4G/5G router ready.
- Works/storm : prolonged outage → switch to 700 Wh station + 160 W panel .
- Security lighting : Low-consumption LEDs for key areas (office/corridor/kitchen).
Priorities: productivity (laptop + screen), connectivity (4G/5G), safe lighting , 6–12 h battery life , silence .
2) Concept: LiFePO4 station + UPS + pass-through + MPPT
- LiFePO4 512–700 Wh : thermal safety, longevity, stability.
- UPS : automatic mains → battery switch to avoid shutting down sensitive devices.
- Pass-through : powers while charging (practical for box/router/LAN/laptop).
- Built-in MPPT : maximum efficiency with 120–160 W panel.
- Display : % + W in/out → you control consumption directly.
3) Size 512/700 Wh: work, network, light
- USB-C Laptop : 45–80 W depending on model/use.
- USB-C portable display : 10–15 W (13–16″).
- 4G/5G Router 12V : 8–12W (stable flow).
- LED : 3–10 W per lamp (office, hallway).
Quick rule : 512 Wh = 1 day “work + network + LED”; 700 Wh = long video margin + extended outage.
4) Key ports: USB-C 100W , 12V regulated , AC sine wave
- USB-C Power Delivery 100W : laptop/monitor/hubs (efficiency & silence). Uses a 5A e-marker cable .
- 12V regulated : 4G/5G router, small LEDs, avoids AC losses.
- USB-A : phones, USB modems, accessories.
- AC 230 V (pure sine) : non-USB-C screens, proprietary chargers → as a last resort .
5) Backup network: 4G/5G 12V router & sharing
- 4G/5G 12V router : more stable than smartphone sharing, ideal for video/VPN.
- Optimization : near a window, clear antenna, band-lock if possible; lower Wi-Fi power if you are alone.
- Failover : turns off the box, switches to 4G/5G, continues in USB-C 100 W.
- Powerbanks 20k/30k : modem/phone relay while the station recharges (solar/12V).
6) UPS & pass-through: uninterrupted continuity
- UPS : Place the station between the mains and your IT power strip (laptop/monitor/router). When the power goes out, the station takes over without switching off .
- Pass-through : useful for holding long video calls while recharging the station when the power returns.
- Tips : Test the switch off while not in production; avoid overloading the AC outlet; favor USB-C/12V.
7) LED lighting & security (home/office)
- 12V 3–10W LED : sufficient for working/moving.
- Areas to light : office, hallway, kitchen; USB children's night light.
- Safety : no flame; station in the shade , ventilated , not covered .
- Organization : a 12 V garland marks the passage → zero fall.
8) Solar 120–160 W (MPPT): smart top-up
- Realistic output : 120 W → 70–95 W usable; 160 W → 110–135 W (angle/short cables).
- Gain : 2–3 hours of good sun → +220 to +405 Wh (160 W), enough to compensate for the router + LED + part of the laptop.
- Placement : oriented kickstands, avoid balcony/vegetation shadows, MC4→DC short & thick.
9) 12V car charging & network connection
- 12V input : 60–120W typical (depending on socket/fuse). Plug in after starting , unplug before stopping .
- Thermal : ventilated trunk, station in the shade, never covered during charging.
- Workflow : during a long break, take the opportunity to recharge while traveling (shopping/appointments), then come back with 40–60% recovered.

14) FAQ on electrical/network failures
UPS and pass-through, are they the same?
No. UPS = automatic switchover without cutting off; pass-through = supply power while charging (useful but not a UPS in itself).
USB-C 100W or AC for laptop?
USB-C direct = better battery life & less noise. AC is used for proprietary chargers.
Is 160W solar enough for a day of teleworking?
Yes, 2–3 hours of good sun adds +220–405 Wh , enough to cover the router + LED and part of the laptop.
Can I connect a NAS/box to the station?
Yes, but check the total power and favor the UPS to avoid any unexpected shutdown of the storage.
Car → office crossing?
Recharge at 12V during the journey, then pass-through to the office to leave fully charged.
