1.5kwh smksolar hybrid inverter

*SMKSolar 1.5kVA Hybrid Inverter

SMKSolar 1.5kVA is a budget hybrid solar inverter for small homes, shops, and offices in Nigeria. “Hybrid” means it works with solar + NEPA + battery at the same

**Parameter** **Typical Value**
**Model** SMKSolar 1.5kVA Hybrid MPPT Inverter
**Rated Power** 1.5kVA = ~1200W continuous. Surge/Peak ~3000W for 5 seconds
**Battery Voltage** 12VDC system. Some versions come in 24V
**Output Voltage** 230VAC ±5%, 50Hz/60Hz
**Output Waveform** Pure Sine Wave – safe for fridge, TV, laptop, decoder
**Solar Charger** Built-in MPPT, usually 50A or 60A
**Max PV Input** 1000W – 1500W @ 12V. Max Voc ~102VDC
**MPPT Voltage Range** 30V – 80VDC for 12V

*2. Features & Benefits*
1. *Pure Sine Wave*: Clean power like NEPA. Won’t buzz fridge or damage laptop chargers.
2. *MPPT Solar Charging*: 98% MPPT efficiency. Harvests more solar than PWM, especially in low light/morning.
3. *Hybrid Operation*: 3 working modes you can set:
– *SBU*: Solar → Battery → Utility. Solar priority to save NEPA bill
– *SUB*: Solar → Utility → Battery. Use NEPA first, save battery
– *UTI*: Utility first, solar charges battery
4. *LCD + Touch Buttons*: Change battery type, charge current, output voltage without PC.
5. *Fast Changeover*: <20ms so TV/decoder won’t go off when NEPA comes.
6. *Lithium Battery Compatible*: Has LiFePO₄ charging profile for Ecolion, Ritar, etc.
7. *Wall-mount*: Compact design saves space in shop/flat.

*3. What 1.5kVA / 1200W Can Run*
Keep continuous load under 960W for long battery life.

*Can run together:*
– TV 120W + fridge 150W + 4 LED bulbs 40W + 2 fans 120W + laptop 60W = ∼490W
– 0.5HP AC 500W + lights + TV = ∼700W → works but drains battery fast
– Water pump 0.5HP 400W + freezer 200W = works

*Cannot run:* 1HP AC, electric cooker 2kW, pressing iron 1.5kW, kettle 2kW. Will overload.

1. *Battery*: 12V 200Ah tubular = 2.4kWh, or 12V 100Ah LiFePO₄ = 1.2kWh. Lithium gives 6000 cycles vs 1200 cycles.
2. *Solar Panels*: 3-4 × 300W = 900W-1200W total. MPPT 60A can take it. Gives 4-5kWh/day with 5hrs sun.
3. *Example*: 12V 200Ah + 4×300W panels → Can run TV, fridge, lights, fan from 6am-10pm on solar.

*5. Installation Tips*
1. *Cable size*: 12V 1200W = 100A+. Use 35mm² or 50mm² DC cable. Thin cable = heat + voltage drop.
2. *Panel wiring*: For MPPT, put 2 panels in series = 60-80V. Max Voc must be <102V or inverter will fault.
3. *Breakers*: Use DC breaker between panels + inverter, and battery fuse 125A.
4. *Battery settings*: For tubular: bulk 14.4V, float 13.8V. For LiFePO₄: bulk 14.6V, float 13.6V, cut-off 10.8V.

*Bottom line*: SMKSolar 1.5kVA hybrid is entry-level but does the 3 basics: solar charging, NEPA backup, pure sine wave. If your daily load is <6kWh, pair it with 12V 200Ah lithium + 1.2kW solar and you’ll cut NEPA bill by 70%+
