5 kWh battery: when it is enough, when you need 10
A 5 kWh module (51.2 V × 100 Ah) is our entry point into off-grid living. Our typical customer this year: a 50-80 m² apartment or a small country house planning to ride through 3-4 hour evening blackouts. In that scenario 5 kWh keeps a fridge plus router plus a couple of LED lights running for 6-8 hours. A house with a heat pump, water boiler, or AC needs more. We push those customers to 10 kWh or higher.
Technically it is one 48-51.2 V module that connects to any 48 V hybrid inverter. Modularity is the main advantage. Want to double capacity tomorrow? Ship one more unit in parallel and you have 10. Felicity LPBA scales to 16 modules. Veichi VCLB to 8. Rosen in rack format is limited only by your cabinet height. We ship from our Kyiv warehouse the same day. We ask up front: which inverter, where will it sit.
What we ask before you order a 5 kWh battery
First question: the inverter. The battery BMS and the communication protocol (CAN or RS485) must match the inverter firmware. Veichi VCLB is the native pair for Veichi inverters (one brand, compatibility guaranteed). Felicity LPBA48100-OL and LUX-E are universal and work with Deye, Sorotec, Felicity, Solax. Rosen in rack format goes where you want a corporate look or a server cabinet aesthetic.
Second: form factor. The floor block (Veichi VCLB-5K-D01, Felicity LPBA) sits in a utility room on its feet. The wall version (Veichi VCLB-5K-W01) mounts in a hallway or heated garage and saves floor space. Rosen rack format goes in 1U or 2U units when you already have a stack. Third: ambient temperature. A heated room (15-25°C) takes any model. An unheated space requires confirmation: not every module has built-in cell heating. Manufacturer warranty 5 to 10 years. Sizing consultation against your inverter is free at our shop.
