3KVA Solar Nyumbani Low Frequency PWM Inverter

3️⃣ Product Overview (120–160 words, Macire mentioned)

The Solar Nyumbani 2200W/3KVA 24V Low Frequency PWM Inverter is a heavy-duty transformer-based inverter designed to deliver stable AC power from a 24V battery bank. Its low frequency architecture provides stronger surge handling than lightweight high-frequency designs—making it more suitable for real Kenyan home loads such as fridges, TVs, lighting, routers, and selected motor appliances when correctly sized. The built-in PWM solar charging function supports basic solar charging and is ideal for cost-effective setups where simple charging control is acceptable.
Macire supplies this inverter with practical sizing guidance, battery/solar matching support, and recommendations for safe installation. Macire can also advise when to upgrade to MPPT depending on panel size and site conditions.

4️⃣ System Architecture & Configuration

Core Inverter System (Low Frequency)

• Transformer-based low frequency design for improved surge capability and load tolerance.

• Stable output for mixed household loads and moderate inductive loads when engineered properly.

DC System (24V Battery Bank)

• Designed for 24V battery systems (typically 2×12V in series or 24V lithium bank).

• Requires correct cable sizing and DC protection for safe operation.

Solar Charging (PWM)

• Integrated PWM charge control for basic solar charging.

• Best suited for smaller panel arrays where PWM efficiency is acceptable.

Protection & Operating Safety

• Typical protections include overload, short circuit, battery over/under voltage, and temperature protection (exact protection set depends on unit variant).

5️⃣ ???? Technical Specifications Table

Note: Where your unit label differs, follow the label as the final specification. Typical operating range recommended by Macire depends on load profile and battery chemistry.

8️⃣ ???? Installation & Engineering Notes

• Install in a dry, ventilated area away from dust, rain, and direct heat.

• Use correct DC cable size (short runs, thick copper) and secure terminals tightly.

• Add DC fuse/breaker close to the battery and an AC breaker/DB on output.

• For PWM solar input, match panel configuration to the controller limits (Voc/amps).

• Macire can guide on battery sizing, solar sizing, protection devices, and wiring layout for safe performance.

9️⃣ ???? Care, Maintenance & Operations (6–8)

• Keep ventilation paths clear; clean dust periodically.

• Check DC terminals for tightness and heating signs monthly.

• Avoid continuous operation near maximum load for long life.

• Monitor battery voltage and state-of-charge to prevent deep discharge.

• For lead-acid batteries, maintain electrolyte levels (where applicable).

• Ensure solar input wiring is secure and weather-protected.

• If any abnormal smell/noise/overheating occurs, switch off and inspect.

• Spares and support availability can be confirmed through Macire.

???? ⚠️ Do’s & Don’ts

✅ Do’s

• Size the inverter with headroom (Macire recommends 20–30% spare capacity).

• Use proper DC protection (fuse/breaker) and earthing.

• Use thick copper cables for 24V DC runs to reduce voltage drop.

• Keep batteries in a ventilated space and follow battery safety rules.

• Balance loads and avoid switching on multiple heavy appliances at once.

• Confirm PWM limits before connecting solar panels.

❌ Don’ts

• Don’t connect loads above 2200W continuous.

• Don’t run heating appliances (kettle, cooker, iron) unless fully sized for them.

• Don’t use thin cables on 24V systems—this causes heat loss and shutdowns.

• Don’t exceed solar controller voltage/amp limits (can damage the unit).

• Don’t install in sealed cabinets with no airflow.

• Don’t mix old and new lead-acid batteries in the same bank.

1️⃣1️⃣ ???? Compatibility

• 24V battery banks: Lead-acid (AGM/GEL/Flooded) or 24V lithium (LiFePO₄) with proper settings

• Solar panels: Compatible with PWM charging within controller limits

• AC distribution: DB, breakers, changeover/transfer switches

• Protection devices: DC breakers/fuses, surge protection, earthing kits (Macire-supplied options)

• Typical loads: TVs, fridges (correctly sized), lighting, routers, CCTV, laptops

1️⃣2️⃣ ???? Performance / Runtime Table (Typical Guidance)

Example runtimes assume a 24V 200Ah battery bank (~4.8kWh nominal) with ~80% usable energy depending on battery type and losses. Performance depends on installation and load sizing as guided by Macire.

*Estimates vary by battery health, inverter efficiency, and real appliance cycling (especially fridges).

1️⃣3️⃣ ❓ Mini FAQ (5)

1) Is 3KVA enough for my home?
For essential loads (lights, TV, WiFi, charging, and a fridge), it can be suitable. Macire can help size based on your exact appliances.

2) Can it run a fridge or small pump?
Low frequency units generally handle surges better, but motor loads must be assessed. Share the motor watts/HP and Macire can advise.

3) PWM vs MPPT—what’s the difference?
PWM is simpler and often cheaper but less efficient for larger arrays. If you plan bigger solar, Macire may recommend an MPPT upgrade.

4) Do you offer installation support?
Yes—Macire can provide guidance on wiring, protection, and system sizing, and connect you to installation support where applicable.

5) Do you deliver across Kenya and what about warranty?
Macire supports Kenya-wide supply logistics. Warranty terms depend on the supplied unit batch—confirm at purchase.
