HS2114UH48L dual mppt 11.4kw 48v split phase hybrid inverter

GRANKIA HS2114UH48L dual mppt 11.4kw 48v split phase hybrid inverter can work for modern residential and light commercial solar energy systems.

The dual MPPT 11.4 kW 48V split phase hybrid inverter manages solar generation efficiently. It also manages battery storage and grid interaction. This 48V split phase hybrid inverter does this with high efficiency and stability. It supports both on‑grid and off‑grid operation, making it suitable for backup power, self‑consumption optimization, and small off‑grid projects.

The 48V split phase hybrid inverter serves the North American market. It features a split-phase 120/240V AC output. This enables seamless integration with standard household appliances and electrical panels. Its advanced dual MPPT architecture allows independent optimization of two separate solar array strings. The hybrid inverter maximizes energy harvest even under partial shading. It also performs well with varying panel orientations.

48V Split Phase Hybrid 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

Two high-efficiency MPPT trackers have a wide PV input voltage range. This range is typically 90–450Vdc or similar. These trackers allow optimal harvesting from two differently oriented or shaded roof arrays. Maximum PV input power up to 15kW (7500W + 7500W), maximizing solar production year-round.

48V Low-Voltage Battery System

Compatible with most popular 48V battery types:

• Lithium-ion (LiFePO4 with BMS communication)

• AGM / Gel / Flooded lead-acid

• Supports closed-loop communication with leading brands (Pylontech, etc.) for precise SOC management and longer battery life.

Advanced Hybrid Functionality

• Grid-interactive (sell back excess solar power when allowed)

• Automatic generator start (dry contact for 2-wire start)

• Time-of-use scheduling & programmable charge/discharge periods

• Built-in smart load management port (for non-essential loads)

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.

Smart Energy Management

Supports time-of-use scheduling, load shedding, and optional remote monitoring via Wi-Fi/RS485.

Product Details

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:

  1. Solar power supplies household loads first.

  2. Excess solar power charges the batteries.

  3. 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:

  1. Solar power (priority source), and

  2. 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.

Hybrid Operating Modes

This 48v split phase hybrid inverter supports multiple operating modes in one unit: grid‑tie, off‑grid, and hybrid with battery backup. This can prioritize solar power. The inverter charges batteries when excess energy is available. It automatically draws from batteries during grid outages to keep critical loads running.

Typical working scenarios include:

• Self‑consumption mode, where solar energy is used locally first and surplus is stored or exported.

• Backup mode, where batteries and PV maintain essential loads during power failures.

• Time‑of‑use optimization, charging the battery when tariffs are low and discharging during peak pricing (depending on local policy and configuration).
