Solar Panel:
550W panel (assume 36V–48V depending on type).
Daily output (in full sun, ~5 hours/day):
→ 550W x 5 = ~2.75 kWh/day (ideal case).
Battery:
200Ah Luminous battery (12V system assumed unless otherwise stated).
Energy storage capacity = 200Ah × 12V = 2.4 kWh
Usable capacity (if lead-acid, ~50% DoD): 1.2 kWh usable
(If it's lithium, closer to 2.0–2.3 kWh usable).
Charge Controller:
50A, likely MPPT.
More than enough for a 550W panel (550W ÷ 12V ≈ 45.8A max current, but panel V is likely higher).
Inverter:
1500W (pure sine or modified?).
Capable of running mid-sized appliances.
Peak power usage must be monitored to avoid overload.
Wiring:
20m Dropping Wire (assumed from panel to controller).
Important: Wire gauge and voltage drop must be managed carefully at 20m distance.
Component | Status | Notes |
---|---|---|
Panel | ✅ Good | Can keep 200Ah battery charged, depending on usage. |
Battery | ✅ Good | 200Ah gives a decent reserve, match with load pattern. |
Controller | ✅ Adequate | 50A is enough for current from 550W panel. |
Inverter | ✅ Caution | Can handle devices up to 1500W, but monitor surge loads (fridge, pump, etc.). |
Wiring | ⚠️ Check Gauge | 20m is long. If gauge is too thin, power loss and heating can occur. Use 6mm² or thicker for safety and performance (especially for 12V or 24V systems). |
