The CE-H12K specifications published by Nigerian suppliers list 12,000W output, 48V DC input, 230V AC output, 93% peak efficiency, 210A maximum charging / 240A maximum discharging, 500V maximum PV voltage and 85–450V MPPT range.
☀️ Solar Input
The CE-H12K is designed for a large solar array:
- Maximum PV voltage: 500V
- MPPT operating range: 85–450V
- Maximum PV input current: 27A + 27A
- Built-in MPPT solar charger
- Dual PV input capability on the listed CE-H12K configuration
This gives the inverter substantially more solar-input capability than the CWORTH 4kVA and 6kVA models.
🔋 Battery System
The inverter uses a 48V battery bank.
Recommended battery options include:
- 51.2V LiFePO₄ batteries
- 48V lithium battery systems
- AGM batteries
- GEL batteries
- Lead-acid batteries
For a lithium installation, CWORTH’s 48V-class LiFePO₄ batteries are a natural pairing.
⚡ 12,000W Output
Unlike the CWORTH CE-L10K, which is rated at 10kVA / 8kW, the CE-H12K is rated at the full 12,000W output. CWORTH’s current product range confirms the CE-H12K as a 12kW / 48V inverter.
It is suitable for larger loads such as:
- Multiple refrigerators/freezers
- Air conditioners
- Water pumps
- Washing machines
- TVs and entertainment systems
- Office equipment
- Computers and networking equipment
- Fans and lighting
- Larger commercial/residential loads
Actual simultaneous load should still account for startup surge, power factor and the battery’s continuous discharge rating.
Key Features
- 12kVA / 12,000W rated output
- 48V battery system
- Pure sine-wave output
- Built-in MPPT solar charger
- 85–450V MPPT range
- 500V maximum PV Voc
- 27A + 27A PV input
- Up to 210A battery charging
- Up to 240A battery discharge
- Wide 90–280V AC input
- Solar + battery + grid operation
- Lithium battery support
- Fast 10ms UPS transfer
- LCD monitoring
- BMS communication support
- Multi-stage battery charging
- Overload and short-circuit protection
- Over-temperature protection
- Suitable for large residential and commercial solar systems
CWORTH also states that its inverter family supports pure sine-wave output, built-in MPPT charging, wide 85–450V PV operation on the larger models, and parallel/three-phase configurations within the supported range.
