Choosing a solar inverter in Lebanon comes down to one question: what do you need to keep running when the power goes off? This guide explains how to size a Sungrow hybrid inverter and SBR battery for a home or small business, when an on-grid inverter makes sense instead, and what each Sungrow model costs at Ghaddar Machinery Co. Specifications come from Sungrow’s own product pages and datasheets.
The quick answer
- A home on a single-phase supply that needs backup during power cuts? Start with the Sungrow SH6.0RS 6 kW hybrid inverter and an SBR battery sized to how many hours you need to cover.
- A large home, villa or small business on a three-phase supply? Look at the Sungrow SH25T 25 kW three-phase hybrid inverter, again with SBR batteries.
- A factory, farm or building that mainly wants to cut daytime grid or generator costs, without batteries? The on-grid SG CX range (25 kW to 125 kW) is the lower-cost option per kW, but it does not give backup on its own when the supply goes down.

Hybrid or on-grid: which kind of inverter do you need?
A hybrid inverter (Sungrow SH series) connects solar panels, a battery and your supply together. During the day it runs your loads from solar and charges the battery; when the supply fails it keeps your backup circuits running from the battery and panels. That is what most Lebanese homes want, because the point of the system is to keep the lights, fridge, internet and water pump on through power cuts.
An on-grid inverter (Sungrow SG CX series) turns solar power into AC and feeds it straight into your building’s supply. It has no battery connection. Like all grid-tied inverters it needs a live AC supply to work, and it switches off when that supply goes down. It is the right tool when you mainly want to cut daytime electricity or generator costs on a large site. Running an on-grid inverter alongside a diesel generator needs a controller that stops the solar from pushing power back into the generator, so ask us before planning that kind of system.
How to size a Sungrow hybrid system
1. List what must keep running during a power cut
Write down the appliances you want on backup and their power: for example the fridge, lights, internet router, TV, laptop chargers and water pump. Add up the power of everything that can run at the same time. This is your backup load in kW. Large loads such as air conditioners, electric water heaters and ovens make the biggest difference to the size and cost of the system, so decide whether they really need backup.
2. Choose the inverter
The inverter must be able to carry your backup load, with some margin for motors that draw a surge when they start.
- SH6.0RS: single phase, rated 6 kW, with a short peak of 8,400 VA for 10 seconds to help motors start. It switches to backup in less than 10 ms, fast enough that most equipment keeps running. It has 2 MPPTs (two separate panel strings) and accepts up to 150% of its rating in panels, so roughly 9 kWp of solar.
- SH25T: three phase, rated 25 kW, for larger homes and small businesses. Sungrow specifies seamless on-grid/off-grid switching, 3 MPPTs with 5 strings, up to 200% of its rating in panels, and an IP65/C5 enclosure for outdoor installation.
3. Choose the battery size
Estimate the average power you use during a typical outage and multiply it by the number of hours you want to cover. For example, an average of 1 kW for an 8-hour evening and night outage needs about 8 kWh, which points to the 9.6 kWh SBR096. Covering 1.5 kW for 10 hours needs about 15 kWh, which points to the 16.0 kWh SBR160.
Sungrow SBR batteries are lithium iron phosphate (LFP) and built from 3.2 kWh modules stacked in one tower, from 2 to 8 modules. Sungrow rates them for up to 100% usable energy and up to 30 A continuous charge and discharge, and you can add modules later if your needs grow.
4. Size the solar array
The panels have to power your daytime loads and refill the battery. As a rough rule, each kWp of panels in Lebanon’s sunny climate produces around 4 to 5 kWh on a clear day, less in winter and on cloudy days. To refill a 9.6 kWh battery and run daytime loads, a 6 kW system typically needs something like 5 to 8 kWp of panels. An installer should confirm the numbers for your roof, orientation and shading.
Example systems
- Apartment or small home, single phase: SH6.0RS with SBR096 (9.6 kWh), equipment from $4,860 before panels and installation. Suits lights, fridge, internet, TV and a water pump through an evening outage.
- Family home with longer outages: SH6.0RS with SBR160 (16.0 kWh), equipment from $7,000 before panels and installation.
- Villa or small business, three phase: SH25T with SBR256 (25.6 kWh), equipment from $11,910 before panels and installation.
Compatibility: what works with what
Sungrow’s SH hybrid inverters work with high-voltage batteries. The SH6.0RS accepts a battery voltage of 80 V to 460 V and is compatible with Sungrow’s SBR, SBH and SBS050 batteries. It does not work with 12 V, 24 V or 48 V low-voltage batteries. The SH25T also works with SBR batteries. If you already have a 24 V or 48 V battery bank, a low-voltage inverter such as the Sunpac InverPro range may be the better fit.

Frequently asked questions
How much does a Sungrow inverter cost in Lebanon?
The current price of every Sungrow inverter and SBR battery we sell is in the price table above and on each product page. The SH6.0RS 6 kW hybrid inverter is the usual starting point for homes, and the SH25T 25 kW hybrid inverter for larger three-phase systems. Prices are for the equipment only; panels and installation are extra.
What size Sungrow battery do I need?
Multiply the average power you use during an outage by the number of hours you want to cover. An average of 1 kW for 8 hours is about 8 kWh, so the 9.6 kWh SBR096 would suit. SBR batteries are built from 3.2 kWh modules, from 6.4 kWh up to 25.6 kWh in one tower, and can be extended later.
Does the Sungrow SH6.0RS work during a power cut?
Yes, when it is connected to a battery. The SH6.0RS switches to backup in less than 10 ms and can supply up to 6 kW to your backup circuits from the battery and solar panels.
Can I use my existing 48 V battery with a Sungrow SH6.0RS?
No. The SH6.0RS works with high-voltage batteries between 80 V and 460 V, such as Sungrow’s SBR series. For 24 V or 48 V battery banks, a low-voltage inverter such as the Sunpac InverPro range is the usual choice.
Does an on-grid Sungrow inverter give backup power?
No. On-grid inverters such as the SG CX series have no battery connection and switch off when the supply goes down. They are designed to reduce daytime electricity or fuel costs. For backup, choose a hybrid SH inverter with an SBR battery.
