Solar Off-Grid Inverters

Power Your Home with Eastman Off-Grid Solar Inverters

An off-grid solar inverter converts the direct current generated by solar panels and stored in batteries into alternating current for household or business appliances.

Eastman Solar offers off-grid inverter solutions for homes, shops, offices, farms, and remote locations. The range covers Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT) technologies, different battery voltages, and capacities from 500VA to 10000VA across selected series.

Why Choose an Off-Grid Solar Inverter?

An off-grid solar inverter system can provide greater control over how solar energy is generated, stored, and used. Key advantages include:

1. Backup During Outages: Stored battery energy can support essential appliances when grid power is unavailable.
2. Reduced Grid Dependence: Solar panels and batteries can meet part or all of the property’s electricity requirements.
3. Suitable for Remote Areas: An off-grid setup can supply electricity where grid access is weak or unavailable.
4. Efficient Battery Charging: PWM or MPPT charge-control technology manages the energy supplied to the battery.
5. Lower Generator Usage: Solar generation and battery storage can reduce reliance on diesel generators.

Explore Eastman Off-grid Solar Inverter Range

Eastman Solar offers four main off-grid inverter series for different power requirements, battery configurations, and charging preferences.

*Warranty is subject to applicable terms and conditions.

Solar Smart

The Solar Smart series uses Pulse Width Modulation (PWM) charging technology and is available in capacities ranging from 500VA to 2500VA. It is suitable for homes and smaller establishments that need solar backup for essential loads such as lights, fans, televisions, routers, and similar appliances.

Solar Smart Max

Solar Smart Max combines MPPT technology with a wider capacity range from 500VA to 10000VA. It is suitable for users seeking improved solar energy utilisation, intelligent battery charging, and support for larger connected loads.

Solar Prime

The Solar Prime series offers PWM-based models from 850VA to 3000VA. It provides options for common residential and small commercial backup requirements using 12V or 24V battery configurations.

Solar Prime Max

Solar Prime Max offers MPPT-based options from 1000VA to 10000VA across 12V, 24V, and higher-voltage configurations. This off-grid inverter range can support larger homes, offices, shops, farms, and other installations requiring greater system capacity.

How to Choose the Right Off-Grid Solar Inverter

Follow these steps to select a suitable off-grid solar power inverter:

1. Calculate the Connected Load: List the appliances that must operate together and add their power ratings. Include the starting load of equipment such as refrigerators, pumps, and motors.
2. Decide the Backup Duration: Estimate how many hours the appliances must run without solar generation or grid power. Longer backup requires greater battery capacity.
3. Choose the Inverter Capacity: Select a VA or watt rating that can support the total running load while allowing a reasonable safety margin.
4. Match the Battery Bank: Confirm the required battery voltage, capacity, battery type, and number of batteries. The battery configuration must match the inverter specifications.
5. Size the Solar Panels: Ensure the panel array falls within the inverter’s supported solar input, voltage, and charging limits.

Choose an Eastman Solar PWM or MPPT inverter with the required capacity, battery configuration, safety protections, and applicable quality certifications.
