Inadequate ventilation leading to overheating
If you want to sell excess solar power to the grid: Choose a hybrid inverter that supports on-grid operation and meets your country’s certification requirements. Hybrid inverters can also work off-grid during power outages, giving you both export capability and backup power.
If you want complete energy independence or live in an area with frequent power outages: Choose an off-grid inverter. It uses batteries as the main power source and can run entirely independent of the utility grid. Teemway Solar off-grid inverters include utility power backup (city power supplement) — automatically switching to grid power when solar and battery supply are insufficient, ensuring uninterrupted power.
When selecting an off-grid solar inverter, consider the following factors:
Application & Load Type –
For basic home appliances like LED lights, TVs, and fans, a modified sine wave inverter may be sufficient.
For inductive loads with motors (e.g., refrigerators, pumps, air conditioners), choose a pure sine wave inverter to ensure smooth operation and avoid equipment damage.
Load Power Requirements –
Calculate the total wattage of your appliances.
Select an inverter with a rated output power greater than your total load to ensure stable performance.
Features & System Design –
Decide if you need an inverter with a built-in MPPT or PWM solar charge controller.
Check if parallel connection is required for system expansion.
Determine how many solar panels you will connect and ensure the inverter’s PV input range is compatible.
Consider optional features such as Wi-Fi remote monitoring for real-time performance tracking.
Budget & Quality –
Balance cost with durability, efficiency, and warranty coverage.
Teemway Solar offers multiple models to fit different budgets while maintaining high reliability.

Lithium batteries offer higher energy density, longer cycle life, faster charging speed, and lower maintenance compared to lead-acid batteries. They are lighter, more compact, and ideal for solar energy storage in both residential and commercial applications. Teemway Solar lithium batteries come in a wide range of capacities and configurations, ensuring there is always a model to suit your needs. We use 100% brand-new, high-quality lithium cells with a minimum cycle life of 6,000 cycles, and higher cycle life options are available upon request. Models are available with IP21 or IP65 protection ratings for different installation environments, and all batteries come with international certifications such as UN38.3, MSDS, and CE, with selected models also certified by CB, TUV, and UL.
Cycle life: Lithium batteries can last 6,000–8,000 cycles, while lead-acid typically lasts 500–1,200 cycles.
Depth of Discharge (DoD): Lithium can reach 80–100%, lead-acid 50–60%.
Weight & Size: Lithium is smaller and lighter.
Maintenance: Lithium is maintenance-free; lead-acid may require water refilling and equalizing.
Cost over lifetime: Lithium has a higher upfront cost but lower cost per cycle.
Teemway Solar off-grid and hybrid solar inverters come with a standard 1-year international warranty, unless otherwise specified in your contract or proforma invoice. Extended warranty 2/3/5 Years options are available for OEM/ODM orders.

Without battery (grid-tied system): Connects directly to the grid, converts solar power into electricity for immediate use, and sells excess to the grid. Lower upfront cost, but no backup during power outages.
With battery (ESS): Stores solar energy for night-time use or emergencies, provides backup power, and increases self-consumption rate.
Yes. Teemway provide high-efficiency solar systems without battery storage, using solar panels and Teemway inverters. You can later upgrade to add lithium batteries if needed.
Yes. All Teemway Solar off-grid inverters come with a utility power backup (city power supplement) function. This means that when battery power is low or during prolonged periods of insufficient sunlight, the system can automatically switch to grid power to ensure continuous electricity supply.
Off-grid: Works independently from the grid, uses batteries as the main power source, ideal for remote areas or frequent power outages.
Hybrid On/Off Grid: Combines both on/off grid functions — can export to the grid and provide backup power.
It depends on your average daily energy consumption, roof space, and backup requirements. Our technical team can recommend the best system after reviewing your electricity bills and energy usage.
Off-grid and hybrid systems can automatically switch to battery power to keep your home running.
A Commercial & Industrial (C&I) solar system is a photovoltaic (PV) power generation solution designed for businesses, factories, warehouses, shopping malls, data centers, and other large-scale electricity users. It can be on-grid, off-grid, or hybrid (with energy storage).

Teemway’s engineering team can conduct an energy audit to recommend the optimal PV + ESS configuration.
Based on the Teemway Solar 580W monocrystalline high-efficiency PV panels (dimensions 2279×1134 mm, approximately 2.58 m² per panel), the effective usable area after considering mounting racks and spacing is about 75% of the total area.
If you have 3,000 m² of installation area, the actual usable area for panels is approximately 2,250 m², requiring about 872 panels of 580W each, resulting in an installed capacity of around 506 kWp.
Assuming 4 hours of effective sunlight per day, the system can generate approximately 2,024 kWh of electricity daily.
If you need a 1 MWp system, you would require roughly 1,725 panels of 580W, occupying about 5,934 m² of land (including racks and spacing).
The daily power generation is calculated by multiplying the total installed capacity (kW) by the effective sunlight hours per day. These figures may be adjusted based on actual site conditions.

Teemway Solar specializes in professional outdoor solar lighting solutions, including solar street lights, solar flood lights, garden lights. Our products are designed for government projects, wholesale procurement, and residential use.
We use premium lithium battery cells with high cycle life, high-quality photovoltaic panels without dead or cracked cells, and high-flux brand LED chips to ensure superior performance and reliability.
All products come with a standard 2-year warranty. Extended warranty options of 3 or 5 years are also available for greater peace of mind.
The standard lighting duration for Teemway Solar solar lights is 12 hours per night. However, the lighting time, hourly power consumption, and operating modes can be customized according to your regional conditions or specific project requirements.
As a professional manufacturer with an in-house R&D team, we are fully equipped to accommodate and develop tailored solutions to meet any unique needs.
Sunlight intensity, panel size, battery capacity, weather conditions, and installation location all impact performance.
Before placing an order, please inform your sales consultant of your location. This allows us to adjust the configuration based on local sunlight duration, temperature, and weather conditions to ensure optimal brightness, illumination, and lighting duration of the fixtures.
Solar CCTV system use solar panel to power surveillance cameras and recording device, ensuring security monitoring in remote or off-grid location.
Two connectivity options are available: Wi-Fi and 4G. If you choose the 4G version, please prepare a local 4G SIM card yourself, which can be easily inserted to activate the system.
They offer flexible installation without wiring, energy savings, continuous monitoring, and lower operational costs.
Depends on battery storage; typically 1-3 days of backup during overcast conditions.
The integrated system combines solar-powered LED lighting with surveillance cameras, both powered by solar panels and backed by rechargeable batteries. During the day, solar panels charge the batteries, which then supply energy to the lights and CCTV at night or during low-light conditions. This setup enables off-grid, energy-efficient outdoor lighting and security monitoring without external power sources or complex wiring.
Although the system is integrated, the lighting and surveillance functions operate independently: the solar light features an automatic light sensor that turns the light off and charges the batteries during the day, then automatically turns the light on at night. Meanwhile, the CCTV system runs continuously, using motion detection to monitor and record any movement around the area at all times. Both components are powered by solar energy stored in batteries, enabling efficient, off-grid operation without external power.
