1) Audio/lighting profiles & requirements

• Home studio : laptop/DAW (45–100 W), audio interface (5–12 W), active monitors (2×20–80 W), MIDI keyboard/USB controllers, ambient LEDs.
• Rehearsal : guitar/bass amps (AC), 9–12 V pedals, 8–16 channel table (15–40 W), active monitors, some LED spotlights.
• DJ/Live : laptop + controller (USB-C), 1–2 turntables, DJ table, 4G/5G router (streams), stage LEDs.
• Recording : multi-channel recorder, microphones/receivers, 12V camera/screen, router; priority silence & sinus quality .

Goals: Stable pure sine wave AC , minimal acoustic noise , reduced interference , 100W USB-C for PC, regulated 12V for pedalboards/equipment, and Watts display to control your margin.

2) Electrical quality: pure sine , THD, stability

• Pure sine : essential for powering sensitive amps, interfaces, consoles and chargers. “Pseudo-sine” inverters generate hum and heat.
• Low THD : Reduced total harmonic distortion = minimized audio noise .
• Stable voltage/frequency : constant 230 V/50 Hz prevents pops and dropouts from switching power supplies.
• Peak reserve : the station must tolerate peaks (lighting of amps/LEDs) without cutting out.

3) Useful ports: USB-C 100W , 12V regulated, AC

• USB-C Power Delivery 100W : Powers laptops /DAWs and some controllers/hubs. Uses a 5A e-marker cable .
• 12V regulated (10–15A): foot controllers (9–12V via adapter), preamps, routers, 12V displays. Higher efficiency than AC.
• AC 230 V pure sine wave : for active monitors, amplifiers, racks, LED projectors, turntables, tables.
• W in/out display : read live the consumption of your set & the inverter margin.

4) Noise, fans & interference (hum/RF)

• Fans : favor USB-C/12 V for tech (efficiency ↑) → the station ventilates less than in full load AC.
• Placement : station on hard surface , away from microphones/overheads; never covered; in the shade to limit heating.
• Ground loop : separates power and audio signals , balanced XLR/jack cable, avoids dubious adapters. The earth ( PE ) is never cut.
• RF interference : Keep routers/transmitters away from audio cables; use shielded cables and ferrites if necessary.

5) Power budgets: real studio & stage cases

• Home-studio “mix” : 60 W laptop (USB-C) + 10 W interface (USB) + 2 active monitors 2×40 W (avg. 2×15–25 W) + 10 W LED → ~110–150 W.
• Small group rehearsal : 30 W table + 2 active monitors 2×80 W (avg. 2×35–60 W) + 12 V 15 W pedals + 30 W LED → ~150–230 W excluding peaks.
• DJ set : laptop 45–60 W (USB-C) + controller 10–20 W + 2 active speakers (average 2×25–70 W) + lights 30–60 W → ~140–250 W.
• Live recording : recorder 10–20 W + router 10 W + camera/screen 12 V 15–25 W + laptop 60 W → ~95–115 W.

Inverter margin : 500–700 W AC (sine) is sufficient for these profiles; 700–1000 W provides margin (starts/LEDs).

6) Autonomy: formulas, 300/512/700 Wh

 Autonomie (h) ≈ Capacité(Wh) × Rendement / Charge(W)
 USB-C/12 V ≈ 0,90  | AC ≈ 0,85

• Studio profile 120 W (mix) → 300 Wh ≈ 2.1 h; 512 Wh ≈ 3.8 h; 700 Wh ≈ 5.0 h.
• Stage profile 200 W (small set) → 512 Wh ≈ 2.2 h; 700 Wh ≈ 3.0 h.
• Capture profile 100 W → 512 Wh ≈ 4.6 h; 700 Wh ≈ 6.3 h.

Tip : Power the laptop via direct USB-C , keep the AC for speakers/LEDs → +5–10% battery life.

7) Micro-cuts: UPS mode & continuity

• UPS : some stations automatically switch from mains to battery (short transfer) to avoid pops and audio/stream interruptions.
• Diagram : mains → station input; PC/console/router/LED → station outputs. In case of power failure, the station takes over.
• Test : Validates pre- concert/stream behavior (simulated 2–3 min cut).

8) LED lighting (flicker-free), DMX & 12 V

• Flicker-free : Choose flicker-free LEDs for video capture.
• Power : 10–60 W per compact spotlight; 2–4 units cover a small stage.
• Power supply : 12 V direct when possible (efficiency + safety), otherwise AC sinusoidal.
• DMX : network separate from mains cables; avoids loops & keeps power supplies away from audio lines.

9) Wiring: extension cords, audio/power separation, ground

• AC extension cord : H07RN-F cable 3×1.5 mm² (≤10 A) or 3×2.5 mm² (≤16 A). Unwind the reel to avoid heating.
• 12 V DC : short & thick cables (2.5–4 mm² for 5–10 A; 4–6 mm² for 10–15 A). Lockable connectors where possible.
• Separation : audio & DMX on one side, power on the other. Cross at 90° if necessary.
• Ground (PE) : Never intentionally “float” safety grounds. Use DI boxes/isolators to break audio loops, not ground.

10) Solar 120–160 W: top-up between scales

• Objective : to regain 150–300 Wh over 2–3 hours of sunshine with a 120–160 W foldable panel (MPPT).
• Realistic output : 120 W → 70–95 W useful; 160 W → 110–135 W useful (angle, short cables).
• Cables : Thick MC4/DC (16–14 AWG), minimum lengths; no partial shadows.
