Sunpac makes battery-based inverter-chargers and lithium battery storage for homes and businesses that need power independent of the local grid, or reliable backup when it goes down. Ghaddar Machinery Co. stocks Sunpac’s InverPro inverter-charger range and matching lithium and lead-acid batteries for installations worldwide.
What makes an inverter-charger different from a grid-tie inverter
A Sunpac InverPro unit does not need to synchronize with utility grid frequency and voltage the way a grid-tie solar inverter does. It generates its own clean AC power from a DC battery bank, and that battery can be charged from solar panels, the utility grid, or a backup generator. This makes InverPro units easier to deploy across different countries: the battery and inverter side of the system is the same everywhere, and only the incoming charge source (grid voltage/frequency, or generator) needs to match local conditions.
Sizing an InverPro system
InverPro inverter-chargers range from 1.5kW to 11kW of continuous output, at either 24V or 48V battery bus voltage:
- 1.5kW–3kW, 24V — small homes, apartments, and essential-loads backup (lighting, refrigeration, networking).
- 5kW–6kW, 48V — typical family homes running most household circuits.
- 8kW–11kW, 48V — larger homes, small commercial sites, and workshops with heavier motor loads.

Pairing with Sunpac battery storage
Sunpac’s lithium battery line (7kWh, 10kWh, and 14kWh models) is built for InverPro pairing, with a 5-year warranty, an integrated BMS (battery management system), and parallel expansion when a site needs more capacity than one unit provides. For sites that prefer a lower upfront cost or need a proven lead-acid option, the SOLSP12200TT (12V, 200Ah) is also available and can be banked to reach the voltage and capacity an InverPro system needs.
A built-in bridge to backup generator power
Sunpac batteries include a dry contact output that can automatically start a backup diesel generator when battery charge runs low, then stop it once the batteries recharge. For customers who already run Ghaddar generator sets or are considering one, this means the solar-plus-battery system and the generator work together automatically, without a separate controller: solar and grid charge the battery day to day, and the generator only runs when it’s actually needed.
Do you ship Sunpac products internationally?
Yes — Ghaddar Machinery Co. serves the same worldwide markets it supplies engines and generator parts to. Because InverPro systems are battery-based rather than grid-synchronized, they are generally easier to deploy across different countries than grid-tie inverters — but local voltage standards for any grid-charging connection should still be confirmed. Contact us with your location and load requirements to confirm shipping and the right system size.
Genuine Sunpac equipment, not grey-market imports
Every InverPro inverter-charger and Sunpac battery sold by Ghaddar Machinery Co. is genuine Sunpac equipment, sold with manufacturer warranty intact. Grey-market units bought outside authorized distribution can lose warranty coverage and firmware support.

FAQ
What’s the difference between an InverPro inverter-charger and a grid-tie solar inverter?
An InverPro inverter-charger generates its own AC power from a battery bank charged by solar, grid, or generator, so it doesn’t need to synchronize with local grid frequency and voltage the way a grid-tie inverter does. This makes it a better fit for backup power and for markets with variable grid quality.
How do I size an InverPro system for my home or business?
Sizing depends on your daily load: small homes and essential-loads backup typically use the 1.5kW–3kW 24V models, family homes use 5kW–6kW at 48V, and larger sites use 8kW–11kW at 48V. Send us your load details and we can confirm the right size.
Can Sunpac batteries start my backup generator automatically?
Yes. Sunpac lithium batteries include a dry contact that can start a backup generator when charge runs low and stop it once the batteries recharge, so solar, grid, and generator power work together automatically.
Do you ship Sunpac inverters and batteries outside Lebanon?
Yes, Ghaddar Machinery Co. serves worldwide markets, the same as its engine and generator parts business. Contact us with your location so we can confirm shipping and any local requirements.
What’s the difference between the lithium and lead-acid battery options?
The lithium batteries (7kWh, 10kWh, 14kWh) offer a 5-year warranty, a built-in BMS, and easy parallel expansion. The SOLSP12200TT lead-acid battery (12V, 200Ah) is a lower-upfront-cost option that can be banked to reach the same voltage and capacity.
