Jak długo bateria litowa 200AH będzie działać falownik 1000W?
Zrozumienie podstaw: Battery Capacity and Inverter Efficiency
Jak długo bateria litowa 200AH będzie działać falownik 1000W?
A 200Ah lithium battery paired with a 1000W inverter is a common setup for off-grid solar systems, RVS, and emergency backup power. But how long will it last? Let’s break down the math.
Krok 1: Calculate Total Energy Storage
- 12System v: 200Ah × 12V = 2,400Wh (watogodziny).
- 24System v: 200Ah × 24V = 4,800Wh.
Krok 2: Account for Inverter Efficiency
Inverters lose 10-15% energy during DC-to-AC conversion. For a 1,000W load:
Required Battery Power = 1,000W ÷ 0.85 (85% efficiency) ≈ 1,176W per hour
.
Krok 3: Factor in Depth of Discharge (DoD)
Baterie litowe (LiFePO4) can safely discharge to 80-90% DoD. For longevity, assume 80%:
Usable Energy = 2,400Wh × 0.8 = 1,920Wh
.
Runtime Formula:
Runtime (hours) = Usable Energy ÷ Load Power
.
Przykład: 1,920Wh ÷ 1,176W ≈ 1.63 godziny.
Real-World Scenarios: What Impacts Runtime?
1. Load Fluctuations
A 1,000W inverter rarely runs at full capacity continuously. If your average load is 600W:
Runtime = 1,920Wh ÷ (600W ÷ 0.85) ≈ 2.72 hours
.
2. Temperature Effects
- Zimna pogoda: Below 0°C (32°F), lithium batteries lose 10-20% pojemność:cytować[7].
- Ciepło: Above 40°C (104°F), inverter efficiency drops by 5-10%.
3. Battery Health
Older batteries degrade: A 3-year-old 200Ah battery might only deliver 1,700Wh usable energy.
Dla wskazówki: Pair your bateria litowo -jonowa dla słonecznych with a smart battery monitor to track real-time capacity and health.
Extending Runtime with Systemy akumulatorów
One 200Ah battery may not suffice for all-day power, Ale systemy akumulatorów let you scale storage seamlessly. Na przykład:
- 2 Baterie: 400Ach (4,800Wh) → Runtime ≈ 3.26 hours at 1,000W.
- 4 Baterie: 800Ach (9,600Wh) → Runtime ≈ 6.8 godziny.
Benefits of Stacking:
- Konstrukcja modułowa: Add units as energy needs grow.
- Load Balancing: Distribute power draw to reduce strain on individual batteries.
- Kompatybilność hybrydowa: Mix with solar panels for continuous charging.

Optimizing Your System for Maximum Efficiency
1. Use High-Efficiency Inverters
Pure sine wave inverters (90-95% efektywność) outperform modified sine wave models (75-85%). Nasz GYCX Solar Hybrid Inverter reduces losses by 15%, extending runtime.
2. Pair with Solar Panels
A 600W solar array can offset daytime loads:
- Daily Solar Yield: 600W × 5 sun hours = 3,000Wh.
- Net Drain: 1,000W load – 3,000Wh solar = Energy surplus, eliminating battery drain.
3. Smart Energy Management
- Priority Loads: Run essentials (fridge, światła) during low solar hours.
- Scheduled Usage: Delay high-wattage tasks (NP., microwaves) for sunny periods.
