Yes, as long as the voltage systems are matched.

• Voltage matching: Your 48V battery (typically a 51.2V LiFePO₄ battery) must be connected to the inverter's DC input that is rated for 48V. As long as the battery voltage falls within the inverter's allowable range (e.g., 40V–60V), it will work.
• Critical point – current capability: This is the core of the pairing. A 12kW inverter at 48V draws a maximum current of approximately 250A (12,000W / 48V). This means your battery pack (and its BMS) must be able to deliver at least 250A continuously and stably.48V 300Ah battery: Maximum continuous discharge current is typically 200A.48V 314Ah battery: Maximum continuous discharge current is also typically 200A.

• 300Ah → ~15.36 kWh of usable energy. Ideal for standard homes, weekend cabins, or moderate daily usage.
• 314Ah → ~16.07 kWh of usable energy. Provides a bit more backup time and is better suited for larger homes or heavy energy users (e.g., multiple AC units, workshops).

Both have the same voltage (48V), same BMS, same cycle life, and the same physical footprint – the only difference is the internal cell capacity.

The built‑in MPPT charge controller can handle up to 12,000W (12kW) of solar input with a DC input range of 150V–500V. This means you can connect a large solar array and charge your battery at full speed even on cloudy days.

⚠️ Always check that your panel string voltage stays within the inverter’s MPPT range.

Yes – for a typical off‑grid or emergency backup setup. The inverter delivers 12,000W continuous (24,000W surge), which can power:

• Refrigerator, freezer
• Lights, fans, electronics
• Well pump, sump pump
• Window AC or small central AC
• Power tools and workshop equipment
• TV, internet, security systems

For larger homes with electric heating, central AC, or EV charging, you may need to add a second inverter in parallel or reduce simultaneous loads.

Yes.Unlike lead‑acid batteries (which you should only discharge to 50%), LiFePO4 batteries allow 100% depth of discharge (DoD) without damaging the cells. You can safely use every amp‑hour you paid for.

Run time depends on your total load. Here are some typical examples with the 300Ah (15.36kWh) battery at full charge (assuming no solar input):

• Refrigerator + lights + TV (~500W total) → approximately 30 hours of runtime.
• Refrigerator + well pump + electronics (~1,000W total) → approximately 15 hours.
• Window AC + refrigerator + lights (~1,500W total) → approximately 10 hours.
• Heavy tools and workshop equipment (~2,000W total) → approximately 7.5 hours.

With the 314Ah (16.07kWh) battery, you can expect roughly 5% longer runtimes for each scenario.

If you have solar panels actively charging during the day, your runtime can be extended indefinitely (depending on sunlight availability).

Yes – both the inverter and battery are scalable:

• Inverter expansion – The inverter supports parallel operation. You can connect up to 6 units (72kW total) for more power.
• Battery expansion – You can connect additional 48V LiFePO4 batteries of the same brand/model in parallel to increase total storage capacity. Ensure all batteries are at the same state of charge before connecting.

This inverter is a hybrid model, which means it can work in both off‑grid and grid‑tie modes. It supports AC bypass and can feed excess power back to the grid (where local regulations allow). However, you will need to check with your utility company and may require additional permits and a bidirectional meter.

If you only plan to use it as backup without exporting, you can set it to “off‑grid” mode.

The battery comes with a built‑in Bluetooth BMS. Download the Humsienk mobile app (available for iOS and Android) and pair with the battery. You can then view:

• State of charge (SOC) and voltage
• Instant current (charge/discharge)
• Cell temperatures
• Historical data and alerts

The inverter has its own display and can also be monitored via the app (if the inverter is Bluetooth‑enabled – check the specific model). For full remote monitoring, an optional Wi‑Fi or 4G module may be available separately.

Yes. The inverter accepts AC input from a generator via the AC bypass/charger input. When solar and battery are low, the generator can automatically start and recharge the battery (if your generator supports auto‑start, or manually). This is a great way to add extra redundancy for extended cloudy periods.
