How to choose all-in-one ESS inverter?

The all-in-one ESS inverter is an integrated solution that combines solar inverter, battery and controller into one unit. Normally, the all-in-one energy storage inverter has built-in the intelligent display to modify parameters and working modes. It is very convenient for users to use. Not only can it perfectly solve problems such as power outages and power rationing, but also very smart and safe.

However, the configuration of this integrated machine vary to different electricity consumption and rooftop structure of each house. This article will explore how to choose the all-in-one ESS inverter for your house.

Firstly, the analysis of cost of the all-in-one ESS inverter.

There are three working modes for the integrated ESS inverter in general, DC priority, AC priority and SE priority.

The total cost can be divided into four aspects, batteries, energy storage inverter, component systems, and installation. Detail see the following below:

Battery costs

The battery cost is the core of the energy storage system, accounting for about 45%-50% of the cost.

By the way, the technical route of energy storage battery includes lithium-ion battery, lead-acid battery and liquid battery. At present, lithium iron phosphate lithium batteries are more expensive than ternary lithium batteries due to their high safety and long cycle life.

Energy storage inverter cost

The cost of energy storage inverter accounts for about 10%-15%

Component system cost

The component system, that is, the photovoltaic system is used for solar power generation, and the cost accounts for about 20-25%;

Installation

The installation cost has risen year by year, accounting for 15-20%

How to choose the suitable power capacity for your all-in-one ESS inverter?

Normally, if there are 7 to 10 electrical appliances that consume electricity daily, the total power of the power generation system should be around 5KW.

If the daily power consumption reaches 12 to 15 appliances, especially if smart home, new energy vehicle charging, etc. are also considered, it is best to choose a 10KW power generation system.

Please pay attention to that the installation of home solar photovoltaic has many details, including roof structure, roof angle and orientation, load-bearing capacity, etc. Every detail will affect the future power generation efficiency and user experience. Therefore, before installation, it is necessary to find a professional team to design targeted home energy storage solutions. Get free consultation service here.
