This article will lead you to an in-depth understanding of how to connect Deye inverters to batteries.
And covering aspects such as battery selection, connection operation, and precautions, to help you build an efficient and stable energy storage system.
Deye Inverters: The Powerhouse of Photovoltaics
Deye is the only company in China that provides a full range of products for grid connection, energy storage, and micro-inverters.
Its photovoltaic energy storage inverter business has achieved outstanding results: revenue growth in 2021 reached 262%, and net profit accounted for more than 50%.
Becoming the company’s fastest revenue growth and highest profit contribution business segment.
It is no coincidence that Deye inverters are favored by the global photovoltaic market!

Deye Inverter Battery Selection Guide
Deye inverters have the following parameters that you need to know:
Battery type: lithium-ion battery (colloid battery is not supported)
Take the 30kW-50kW model as an example, its battery voltage range: is 160V – 800V
Just so you know, not all lithium batteries are compatible with Deye inverters.
For example, a 48V100Ah lithium battery cannot be connected because its maximum charging voltage of 58V is lower than 160V.
A 768V280Ah lithium battery is incompatible because its maximum charging voltage of 876V is higher than 800V.
PVMars recommends choosing a lithium battery with a range of 512V to 614V to ensure a perfect match with your Deye inverter.
Deye Inverter and Battery Connection Steps
After selecting the battery, please connect it according to the Deye inverter manual. It should be noted that:
The Deye inverter provides 2 battery ports, and the maximum charge and discharge current of each port is 50A.
Equivalent to 800v * 50a = 40kW – P=UI (power = voltage x current). If you connect both ports, a 50kW Deye energy storage inverter can output up to 80kW of power per hour.
In other words, if you want to power a 50kW load for 1.5 hours, you need a battery with 80kW capacity.
The calculation formula is as follows:
Battery capacity (kWh) = load power (kW) × operating time (h)
For example, to power a 50kW load for 8 hours, you need a battery capacity of 400kWh:
Battery capacity (kWh) = 50kW x 8 hours = 400kWh
You can use 2 512V 400Ah lithium batteries, connected to the 2 battery ports of the Deye inverter, with a capacity of 512 x 400 = 204.8kWh * 2 = 409.6kWh > 400kWh. This way, 50kW of power can be output every hour for your load.
If you run your electrical equipment all day, you need more battery power.
