News and advice
What should you prepare before buying battery storage or an EV charging station?
At a glance. Before choosing equipment, gather information about the site and how the system will be used. This helps select suitable battery storage or an EV charging station and identify missing components in advance.

Battery storage: five things to prepare
- The exact inverter model and documentation for the existing system.
- Consumption data and a clear objective: self-consumption, backup power or both.
- Photos, dimensions and environmental information for the proposed equipment location.
- The desired number of modules and any expansion plans.
- An assessment of the site wiring and installation conditions by your chosen qualified specialist.
An IP rating alone does not establish whether a battery is suitable for any outdoor location. The Deye GB-L-Pro manual sets separate requirements for placement, environment, moisture and other conditions. Assess the location using the manual for the exact battery, not a photograph of another model. Source: Deye GB-L-Pro user manual V1.1, sections 3–5.
EV charging: there is more to consider than a “22 kW” label
Provide the vehicle model and its AC charging capability, the site’s electrical supply details, the distance to the parking space and cable requirements. The station’s maximum power is not a promise that the vehicle will always charge at that rate. Both the vehicle and the available site power limit charging.
When does dynamic load management matter?
It adjusts charging according to the power used by other equipment at the site. NexBlue specifies Edge 2 operation with NexBlue Zen load management. Zen 2 documentation describes load management and solar surplus functions separately. Check the exact controller model, metering equipment and package contents. See NexBlue Edge 2: charging station features and NexBlue Zen 2: dynamic load management and solar surplus.
What should an equipment quote include?
| Item | Why it matters |
|---|---|
| Exact equipment model | Similar models can have different features. |
| Additional components | It is clear whether the controller, metering equipment, bracket or cable is included. |
| Manufacturer documents | You can check the requirements and pass them to your specialist. |
| Commissioning and access | Agree in advance who will configure the equipment and hand over account control. |
The NexBlue professional checklist assesses the distribution board, mounting assembly and charging station separately. It shows why purchasing equipment is not the same as completing an installation. Entrust technical work and verification to your chosen specialist; this article is not a guide to carrying out electrical connections yourself. See NexBlue: installation checklist.
What to do next
Email the exact inverter model and describe your requirements to sales@sgenergy.lt. SGENERGY can help you select equipment. Your chosen qualified specialist must assess the site wiring, protective devices and installation work.
