Product description

Sigenergy Sigen Energy Controller 3.0 kW single-phase is an accessory from Sigenergy. This part belongs with a larger battery, inverter or charging system. The exact type number matters more than a general brand match.

Sigenergy brings storage, energy management and charging together on one platform. The configuration is built up per installation. On this page we only use product specifications that can be traced back to a manufacturer datasheet we keep on file. For this model those include continuous power 3 kW, phases single-phase, IP rating IP66.

What can you do with this model?

Place in the system

This part belongs with a larger battery, inverter or charging system. The exact type number matters more than a general brand match.

Verifiable product data

The table below only shows recorded source values. That means less marketing talk and more information that actually belongs to this model code.

Confirming the combination in advance

Before you order, we check the inverter, battery and required control equipment against the official compatibility list. A shared brand logo is not enough for that.

Making the installation fit

Where fixed mounting is needed, the electrical situation is assessed beforehand. That way the quote matches the actual work in your home, and the Dutch NEN 1010 standard remains the starting point.

Verified data

Continuous power	3 kW
Phases	single-phase
IP rating	IP66
Backup power	Yes
Dimensions (H×W×D)	300 x 700 x 245 mm
Weight	18 kg

A nearly identical type number is no proof that the part fits. Have the combination checked in advance. Put the existing main product and this part side by side and compare the full model codes. It is a small check, but it prevents returns caused by a different plug, different dimensions or a different product generation.

Comparing without filling in missing values

For this version, no complete set of sister models with four shared datasheet fields is available locally yet. That is why there is deliberately no numerical comparison here. The model name and product category are known, but we do not fill in missing values from other webshops or from memory.

Who is this a logical choice for?

This model makes sense when the product family already suits your installation and the verified values match your usage. Don't choose based on one big number in the title. Power, capacity and connection each answer a different question. A short intake conversation quickly makes that difference clear.

Frequently asked questions

Is OM.SG.400400 compatible with my current installation?

Our verified compatibility mapping includes Sigenergy SigenStor 10.0 home battery 9.04 kWh, among others. We confirm the full combination by model code before you order.

What information do you need for a proper check?

We need the connection in your meter cupboard (the "meterkast" in Dutch homes), plus the exact model code of your existing inverter or battery. For storage we also look at your consumption and the available solar generation.

Can I expand this version later?

We only say so when the manufacturer confirms it for this series. Without that source we do not promise extra modules, parallel set-ups or future interchangeability.

Can you take care of the installation?

Yes, where installation is needed, it can be carried out by a certified installation partner to the Dutch NEN 1010 standard. What materials and which meter cupboard modifications are actually needed is determined in advance.

Why are not all possible combinations listed on this page?

Compatibility changes per generation and firmware line. So we would rather show one verified combination than a long list of doubtful cases.
