GRANKIA HS2105UH48L 48v 120 240 all in one split phase inverter 10.5kw is engineered for modern residential and light commercial needs. This 10.5kw all in one split phase inverter operates on a 48V DC battery system. It provides true 120V/240V split-phase pure sine wave output. This feature makes it ideal for North American homes and businesses. They require both 120V and 240V appliances.
This system has a unique capability to run loads directly from solar PV and the grid. It works without any battery connected. This feature is ideal for cost-effective daytime solar utilization. It also supports phased system expansion.
Seamlessly operates in grid-tied, off-grid, or hybrid modes. The all in one split phase inverter 10.5kw supports time-of-use (TOU) settings for intelligent charging and discharging. This helps users take advantage of low off-peak rates. They can store excess solar energy and significantly reduce utility bills. Grid export and zero-export (anti-backflow) options are available with two-level anti-backflow protection for safe, compliant operation.
All in One Split Phase Inverter Key Features
High-Efficiency Pure Sine Wave Output
Delivers clean, stable 120V/240V split-phase AC power with pure sine wave waveform, safely powering sensitive electronics, motors, and heavy appliances.
Dual MPPT Solar Charge Controllers
The all in one split phase inverter is equipped with dual MPPT trackers. This optimizes solar harvest from two independent arrays. It supports high PV input and maximizes energy yield even in partial shading conditions.
Time-of-Use (TOU) Optimization
Advanced time-of-use charging and discharging settings offer flexibility. They allow users to program the inverter to charge batteries during low-rate periods. The inverter can discharge during peak-rate times, significantly reducing electricity bills.
Broad Battery Compatibility
Works seamlessly with lead-acid, lithium-ion, and gel batteries, providing flexibility to match your existing or preferred energy storage solution.
Unlimited Load Capacity with Smart Adaptation
Features dynamic over-power adaptation. It handles temporary surges and high starting loads. This ensures the system can support demanding appliances without tripping.
Global Language Customization
User-friendly interface with multi-language support, making setup, monitoring, and operation accessible worldwide.

Split Phase Hybrid Solar Inverter Working Modes
1. Solar + Grid Available (Normal Mode)
-
Solar panels generate power and feed it into the inverter.
-
Priority of power usage:
-
Solar power supplies household loads first.
-
Excess solar power charges the batteries.
-
Remaining energy is exported to the grid (feed-in).
-
-
Surplus energy can be exported to the grid (if enabled).
2. Grid Available, No Solar (Low Sunlight)
-
Solar input is unavailable.
-
The inverter supplies loads using:
- Grid power supports the loads
-
The grid can also charge the batteries according to settings (e.g. time-of-use mode).
3. Grid Outage (Backup / Off-Grid Mode)
-
The utility grid is disconnected.
-
The inverter automatically switches to backup mode.
-
Loads are powered by:
-
Solar panels (if available), and
-
Batteries.
-
-
Critical loads continue to run without interruption, ensuring power reliability during outages.
Time of Use (TOU) Mode
Discharging Period (Peak Tariff Time)
-
During high electricity price hours, the inverter prioritizes self-consumption.
-
Solar energy and battery power are used first to supply household loads.
-
The battery discharges to reduce or avoid using expensive grid electricity.
-
If enabled, excess energy can be exported to the grid.
-
This mode helps users lower electricity bills during peak hours.
Charging Period (Off-Peak Tariff Time)
-
During low electricity price hours, the all in one split phase inverter focuses on charging the battery.
-
The battery can be charged by:
-
Solar power (priority source), and
-
Grid power when solar is insufficient.
-
-
Loads are still powered normally while charging takes place.
-
This ensures that the system fully charges the battery and gets it ready for the next peak period.
Ideal Applications
- Off-grid solar homes and cabins — Powers an entire small-to-medium household independently.
- Hybrid solar + grid systems — Combines solar, battery storage, and utility/generator backup.
- RV, marine, truck camper, or mobile power setups requiring 120/240V capability.
- Emergency backup power — Ideal for critical loads during outages (with generator input support).
- Workshops, farms, small businesses — Runs heavy tools, pumps, welders, compressors, and HVAC equipment.
