[Power Essential 120V Circuits] — Deliver up to 3.6kW of continuous pure sine wave output for selected refrigeration, lighting, network, furnace-blower, outlet, and small-pump loads. This is a 120V single-phase inverter, not a 120/240V split-phase model.

[Choose the Exact Battery Variant] — Select the SPI2436M120-500 with a 20–33Vdc input range or the SPI4836M80-300 family with a 40–60Vdc input range. Never connect a 51.2V battery to the 20–33Vdc model.

[Match Solar Input Carefully] — The 24V class model supports up to 6kW PV, 90–450V MPPT, and 500V maximum VOC. The 48V model supports up to 4.5kW PV, 90–260V MPPT, and 300V maximum VOC.

[Plan Running and Starting Loads] — The inverter provides 5.4kVA peak power, 10ms typical transfer, and motor-starting capability up to 2HP. Verify continuous watts and startup surge separately for every connected appliance.

[Coordinate Energy with Built In Protection] — Use solar, grid, and battery inputs with manual-documented safeguards for overload, short circuit, PV reverse polarity, AC reverse conditions, overvoltage, and temperature. USB and RS485 communication are supported.

[Check the Parallel Suffix] — Parallel operation is limited to the documented 48V SPI4836M80-300P version for configurations of up to six units. Do not assume that the 24V or non-P model can operate in parallel.

[Verify Before Professional Installation] — The enclosure measures 428 × 280 × 110 mm, weighs approximately 7.8–8.2 kg depending on variant, and has a listed operating range of -10°C to 55°C. Correct breakers, fuses, wiring, grounding, ventilation, and a qualified installer are required. A 5-year limited inverter warranty applies under its terms.

Essential Load Inverter

The 3.6kW hybrid inverter provides 120V pure sine wave output for compact backup and solar systems, with battery-input options that must be selected for the intended battery voltage.

Essential Circuit Planning

Prioritize compatible 120V loads such as refrigeration, lights, networking equipment, a furnace blower, and a small pump while excluding central 240V HVAC, ranges, dryers, and Level 2 EV charging.

Solar Variant Matching

The 24V class model supports up to 6kW PV, a 90–450V MPPT range, and 500V maximum VOC, while the 48V model supports up to 4.5kW PV, a 90–260V MPPT range, and 300V maximum VOC.

Output Surge Performance

The inverter provides 3.6kW continuous output, 5.4kVA peak power, 10ms typical transfer, motor capability up to 2HP, and at least 91% listed maximum inverter efficiency.

Flexible Energy Inputs

Solar, grid, and battery inputs coordinate through one compact 120V single-phase platform designed around carefully selected essential circuits and a dedicated critical-load panel.

Coordinated Inverter Protection

Manual-documented safeguards address overload, short circuit, PV reverse polarity, AC reverse conditions, overvoltage, and temperature while still requiring correct external protection and installation.

Verify Model Compatibility

Choose the 20–33Vdc SPI2436M120-500 or the 40–60Vdc SPI4836M80-300 family before ordering, and connect a 51.2V battery only to the verified 48V model with compatible settings and BMS protocol.

Compact Hardware Design

The inverter measures 428 × 280 × 110 mm, weighs approximately 7.8–8.2 kg depending on variant, operates from -10°C to 55°C, and includes a 5-year limited inverter warranty under applicable terms.

Parallel Model Requirements

Parallel operation is limited to the documented 48V SPI4836M80-300P version for configurations of up to six units; the standard 24V and non-P variants must not be assumed to support parallel operation.

FAQs

What is the 3.6kW hybrid inverter designed for?

It is designed for compact 120V backup, solar self-use, and essential-load systems. Typical compatible circuits may include refrigeration, lights, networking equipment, a gas-furnace blower, outlets, and a properly sized small pump.

Can this inverter power 240V appliances?

No. This is a 120V single-phase inverter. Do not use it for central 240V HVAC, an electric range, an electric dryer, Level 2 EV charging, or other loads that require 120/240V split-phase output.

How much continuous and peak power does it provide?

The inverter provides 3.6kW of continuous output and up to 5.4kVA of peak power, with 10ms typical transfer and motor-starting capability up to 2HP under the specified conditions. Always verify running watts and starting surge separately.

Which battery voltage should I select?

Select the exact inverter variant before connecting a battery. The SPI2436M120-500 is the 24V class model with a 20–33Vdc battery-input range. The SPI4836M80-300 and SPI4836M80-300P are 48V models with a 40–60Vdc input range. A 51.2V battery must never be connected to the 20–33Vdc model.

What solar input does each variant support?

The 24V class model supports up to 6kW PV, a 90–450V MPPT range, and 500V maximum PV open-circuit voltage. The 48V model supports up to 4.5kW PV, a 90–260V MPPT range, and 300V maximum PV open-circuit voltage. These are electrical limits, not promised recharge times.

What charging and communication features are included?

Depending on the selected variant, the listed AC charging current is 80A or 60A and the listed PV charging current is 120A or 80A. USB and RS485 communication are supported. Confirm the exact model nameplate, charge settings, and battery communication requirements before connection.

What protection functions does the inverter provide?

Manual-documented safeguards cover overload, short circuit, PV reverse polarity, AC reverse conditions, overvoltage, and temperature. These internal safeguards do not replace correctly sized breakers, fuses, disconnects, wiring, grounding, or professional installation.

Can multiple inverters operate in parallel?

Parallel support applies only to the documented 48V SPI4836M80-300P model, with configurations of up to six units. Do not assume that the 24V model or the non-P 48V model supports parallel operation.

What should I verify before installation?

Verify the exact model and suffix, battery-input range, 120V output architecture, PV voltage and power limits, BMS protocol, charging settings, and included accessories. The enclosure measures 428 × 280 × 110 mm, weighs approximately 7.8–8.2 kg by variant, and has a listed operating range of -10°C to 55°C. A 5-year limited inverter warranty applies under its terms.
