AlphaESS inverter 5kW single-phase SMILE-G3-S5-INV




The AlphaESS SMILE-G3-S5-INV inverter 5 kW single-phase is a hybrid inverter from AlphaESS. This hybrid inverter manages solar panels and battery storage within a single installation. The connection and the battery protocol determine whether a combination is technically sound.
AlphaESS builds storage, inverter and control as one coherent ecosystem. That keeps the model choice straightforward, but it does require the right generation of parts. On this page we only use product specifications that can be traced back to a manufacturer datasheet on file. For this model these include continuous power 5 kW, max. charge power 5 kW, max. discharge power 5 kW.
What can you do with this model?
Where it fits in the system
This hybrid inverter manages solar panels and battery storage within a single installation. Your grid connection and the battery protocol determine whether a combination is technically sound.
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 up front
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 installation is required, the electrical situation is assessed in advance. That way the quote matches the actual work in your home, with NEN 1010 as the starting point.

A hybrid inverter is needlessly expensive if battery storage is not part of your plans, now or later. For an inverter, the check starts with your grid connection and your existing solar panels. Only then comes the battery question. That prevents the wrong phase choice, or a model that does not support the battery protocol you need.
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
Will the 91200112 work with my current setup?
One of the matches in our verified compatibility mapping is the AlphaESS SMILE-G3-BAT-3.8S battery module 3.8 kWh. 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.
