Ampinvt HTS-Series 1000W Off-Grid Solar Inverter 12VDC to 120VAC Pure Sine Wave with 30A MPPT

Overview

The Ampinvt HTS-Series off-grid solar inverter converts 12 VDC battery power to 120 VAC AC output with a low-frequency pure sine wave design and a built-in MPPT solar charger. It supports charging a 12V battery bank from either AC power or solar power when connected to the inverter.

Key Features

• Continuous/peak power: 1000W continuous output power; 3000W peak output power.
• Battery system: 12V battery system only.
• AC output: 120 VAC.
• Pure sine wave: Low frequency pure sine wave output.
• Built-in MPPT: Built-in 30A MPPT solar charger (some product materials also reference 30A/40A MPPT).
• Built-in AC charger: Built-in automatic 15A AC charger and automatic AC mains switcher.
• Adjustable charge current: Charge current can be adjusted; adjust 0–15A charging current.
• Battery type settings: Compatible with 12V battery types: AGM, USER, FLD, SLD, LI, GEL.
• Protections: Multiple protection; battery temperature sensor protection.
• Transformer: Built-in toroidal transformer (strong overload and impact resistance).
• Interfaces/controls: LCD display, LED indicators, function keys, and RS485 communication port.
• Parallel operation: Not supported (cannot connect in parallel).

Working Modes

• AC/Line priority mode: Always uses AC power as priority input, provides AC output, and automatically charges the battery.
• Battery priority mode: Priority is given to battery power. After low-voltage protection, it transfers to AC grid power supply. When the battery is full, it transfers back to battery power.
• ECO mode: Load < 10% enters sleep and stops output; load > 10% boots back to normal inversion.
• Generator mode: Generator connects to the AC input of the inverter; output is stabilized through AVR while the battery is recharged.
• Unattended mode: When battery voltage is low, the inverter goes into standby (power saving). When the battery restores to the set voltage (for example via solar charging), the inverter restores normal output for unattended automatic operation.

Details

Designed for 12V off-grid systems, the HTS-Series combines pure sine wave inversion with an integrated MPPT solar charger for streamlined installs.

Clear I/O labeling and an LCD control panel make setup simple, with dedicated terminals for solar, AC input/output, and the 12V battery bank.

Supports charging the battery from solar or from an AC source while providing 120VAC output for connected loads.

Low-frequency pure sine wave output is paired with a built-in MPPT charger and an automatic 15A AC charger with mains switching.

Rated for 1000W continuous output with a 12VDC battery system and 120VAC AC output for everyday off-grid power needs.

Multiple 12V battery profiles and adjustable 0–15A charge current help match charging behavior to your battery type and system needs.

A compact wall-mount footprint (460 × 390 × 210 mm) suits cabins, RV power bays, and small off-grid utility rooms.

A flexible choice for RV solar, small homes, offices, and remote installations that rely on stable pure sine wave power.
