OFF-GRIDSOLAR ENERGY SOLUTIONS

LESSO Solar off-grid solar energy solutions can be operated far from the area without grid electricity supply by generating, storing the energy by its own. Solar panels are used to keep the loads working and battery charging for night backup. Your off-grid solar system has to be sized properly to meet your daily power needs and make use of the stored energy pulled from the battery.

Main Advantage

Solve the problem of nopowercuts

It can be self-generated and self-consumed without relying on the public grid, and the excess power during the daytime can be stored for use at night to form an independent energysupplymicro-grid,whichcansatisfyremote areaswithouta stablepowersupply, and realize a 24-hour uninterrupted supply of energy.

Effectiveutilization ofgeneratedpower

By utilizing renewable energy sources such as solar orwind,our systemsensure a continuous and sustainable power supply,reducing dependence on fossil fuels and minimizing theenvironmental impact.

HYBRID SOLARENERGY SOLUTIONS

LESSO hybrid solar energy solutions are available as on-grid solar with battery storage system (EsS) and integrate the innovation of both off-grid and on-grid technologies. In addition to being directly used, power can also be saved for use at night. It's also possible to sell excess energy back to the utility provider, which is ideal for homeowners. Still the most affordable option, a standard hybrid solarsystemisidealformostdaytime-operatingenterprises.

Main Advantage

Effectiveutilization ofgeneratedpower

During the day, the power generated by the system is supplied to the local load or sellto the power grid through inverters.At night,the energy stored in the energy storage equipment can supply to the electricity demand. The highest spontaneous self use rate of electricitycanreach 95%

Reducing electricitybills

Set the charging and discharging time for the battery according to the peak and valley electricityprices,charge thebatterywhenthe electricityprice islow,and discharge the battery for load use when the electricity price is high,reducing the economic expenses of householdsonelectricityconsumption.

Intelligent security Easy installation
