Solar energy storage battery solutions.

Working principle

Lithium batteries can provide backup energy for the home through repeated charging and discharging, and effectively store electricity in renewable energy systems such as solar energy, achieving energy conservation and self-sufficiency.

We calculate the return on investment of energy storage batteries by the electricity bills saved by charging and discharging. Different electricity bills and usage conditions will produce different returns on investment. Lithium batteries can be used as a backup power source to support residential electricity during power outages.

Lithium batteries have more energy density, greater discharge depth, longer life, low self-discharge rate, environmental friendliness, and no maintenance.

Lithium batteries have longer life, lower cost, safer and more environmentally friendly.

The top protection level of APEX batteries is IP66, which is the highest standard protection level on the market.

Lithium batteries are mainly transported by land, avoiding high temperature, extrusion, and being placed together with flammable and explosive materials.

APEX lithium batteries use internationally renowned components, have a higher tolerance to high temperature environments, and can work normally in an environment not exceeding 60 degrees. However, in order to better protect the battery and maintain its high performance, we recommend that the operating temperature of APEX batteries be controlled below 30 degrees.

Working principle

The energy storage inverter is a photovoltaic panel or the grid can charge the battery through the inverter, and can also use the inverter to power the load. The energy storage inverter can be used in both off-grid and grid-connected modes.

We calculate the return on investment of the photovoltaic system by the electricity bill saved by the photovoltaic system. Different electricity bills and usage conditions will produce different returns on investment. The photovoltaic system can be used as an independent energy source. When the grid is running, photovoltaic power generation is used first to save electricity bills. When there is a power outage, the power of the inverter is used to support household electricity.

The IP20 inverter has a simple structure and low component cost, and is mainly used indoors. The IP65 inverter has a complex structure and can be used outdoors. APEX’s IP65 inverter uses internationally imported components and is suitable for various application scenarios.

Energy storage inverter can perform bidirectional current conversion and power household loads with inverter. It does not rely on the grid and can be powered independently, which is more expensive. However, grid-connected inverter can intelligently convert photovoltaic power into AC power and transmit it to loads or grids. It relies on the grid to provide power and is less expensive.

Inverter transportation can be carried by land, sea, or air. Avoid high temperature, extrusion, and placing with flammable and explosive materials.

APEX inverter uses internationally renowned components and has a higher tolerance to high temperature environments. It can work normally in an environment not exceeding 60 degrees and output full power. However, in order to better protect the inverter and maintain the high performance of the inverter, we recommend that the operating temperature of APEX inverter be controlled below 40 degrees.

Working principle

The photovoltaic module absorbs light energy and converts it into DC power, which is then converted into AC power to supply power to the load through the solar module.

We calculate the return on investment of the photovoltaic system by the electricity bill saved by the photovoltaic system. Different electricity bills and usage conditions will produce different return on investment. The photovoltaic system can be used as an independent energy source. When the power grid is running, photovoltaic power generation is used first to save electricity bills. When there is a power outage, the electricity from the solar module is used to support household electricity consumption.

The APEX solar module uses the latest TOPCON battery technology.

Topcon’s battery efficiency is higher and the attenuation is lower.

HJT/BC has a higher cost and a slightly higher efficiency than Topcon, but Topcon is currently more mature, has more stable performance, and has a lower cost. Topcon will be the mainstream technology in the next three years.

Solar modules can be transported by land, sea or air. They need to be firmly fixed to avoid bumps, high temperature, extrusion and being placed together with flammable and explosive materials.

APEX solar modules adopt the latest production technology and have a higher tolerance to high temperature environments. They can work normally in an environment not exceeding 85 degrees. However, in order to better protect solar energy and maintain the high performance of solar modules, we recommend that the operating temperature of APEX solar modules be controlled below 50 degrees.

Solar panel installation

The current conversion efficiency of APEX solar panels is up to 22.82%, and it is steadily increasing every year.

1% attenuation in the first year, and 0.55% attenuation each year thereafter.

As long as the inverter supports it, you can add solar panels to the system.

The same model of solar panels need to be connected, and the connection voltage of the solar panels of each inverter MPPT must not exceed the voltage specified by the MPPT.

It depends on the operating environment of the solar panels. When the irradiance is 1000 W/m2 and the module temperature is 25°C AM=1.5, the solar panels can reach the maximum power

5400pa on the front and 2400pa on the back.

We recommend that customers purchase suitable brackets according to local wind loads to ensure that photovoltaic panels will not be damaged due to quality problems of the brackets.
