ES

ES-Hybrid family

This product family is designed for 6-15 kWp. The installation is more challenging and you have to deal with high voltages because panels are connected in series and the battery also operates at a high voltage. It requires a professional electrician at least for the installation of energy meters and fuses, for final inspection and grid connection.

All panels should have free access to sunlight. You can have two groups of panels (“strings”) facing into different directions.

The overall system efficiency including energy storage is around 95%. This product family always comes with a modern battery. You can integrate used panels if they are all of the same type. Energy feeding into the grid can be controlled. Off-grid functionality is an integral part of the ES-Hybrid family.

Your ES-Hybrid devices will come preconfigured so that they work out of the box. If you do not object, we will occasionally have a look at the production data of your system. With your permisssion we would also like to publish your production data in anonymized form on our website. In case we see any problems or if firmware updates are necessary we may be able to help you. Of course you have admin access to your system and can monitor all data via browser or via an app on your mobile device.

ES-Hybrid is based on Growatt products. For example an ES-Hybrid-14-10 system uses the following components:

1 x Growatt 3-Phase Inverter MOD-10KTL3-XH BP

Manual (German)

The inverter has no transformer. This means that the DC side has a changing voltage against earth.

1 x Growatt Shine Link Stick X + LAN Box
Manual (German)

1 x Growatt battery stand for APX HV batteries

1 x Growatt APX 98034-P2 Battery Management system

2 x Growatt APX 5.0P-B1 Hochvolt 5kWh Batterie (including BMS)

Growatt SYN 50 XH 30 three phase back up box (288€)
single phase, connected to critical loads

1x Smart Meter TPM-CT-E

We list prices we found in the German web (no V.A.T.) in Jan 2025.


We refer to the smallest system, an ES-Hybrid-7-5
We think that 16 panels (8 per string, facing East/West) will make a reasonable configuration.

MOD5 KTL3 XM BP inverter 850
SYN 50 XH 30 backup switch 300
Shine X WIFI Stick and LAN Box 30
TPM-CT-E 260
APX battery base 30
APX 98020-P1 BMS 280
APX 5.0P-B1 battery unit 1.200
16 panels (2 x 8) 800
===================================
~ 3.700€

You must add cost for DC cables (70€ and panel mounting material 640€ or more, depending on your situation).

Your total investment will be ~ 4.500€ plus your work.

The sum of the peak powers of the panels is 7.120W because we suggest to use 445W panels. This theoretical maximum power will in reality hardly be achieved at any moment. It is good practice to choose the panels larger than the inverter’s peak power limit. Using 16 panels will be fine, especially when using East/West orientation. If you use older panels you might even connect 20 or more panels. By the way, the inverter has bult-in overload protection, so there is no danger in connecting that number of panels. Just make sure you keep within the limits of maximum voltage and short circuit current.

You can expect 7.000 kWh annual production and a self use percentage of 70%. If you pay 30 ct / kWh your annual saving will be 1.500€; this means that your ROI is close to three years – which is excellent!
