The SUNWAY High-Voltage Battery fits your exact power needs. You start with a 15kWh base setup. You can add 5kWh modules. The system scales up to 42kWh.
You mount the base directly on the ground. The system uses safe Lithium Iron Phosphate (LFP) cells. The thermal stability is excellent. The hardware offers a design life of over 15 years.
The physical installation is very fast. You stack them directly on top of each other. There are no external cables. Internal quick connectors link the power automatically. Your technicians spend much less time on site.
15kWh to 42kWh Expansion
The modules stack together directly. You do not use external cables. Internal quick connectors link the boxes. You save hours on installation. The capacity scales from a 15kWh base up to 42kWh.
LiFePO4 Core & Aerosol Fire Kit
It uses stable LiFePO4 cells. A built-in BMS manages the power. The hardware includes integrated fuses.
6,000 Cycles & 90% DOD
The battery supports a 90% Depth of Discharge (DOD). You extract more usable energy every day. The cells last over 6,000 cycles at standard testing conditions (0.5C, 25°C). You replace the system less often. This lowers your total project cost.
IP65 & -20°C to +55°C Operation
The casing carries a strict IP65 rating. It blocks dust and heavy rain. You can install it outdoors. It powers your equipment in freezing -20°C weather. It handles +55°C summer heat without shutting down.

FAQs
Q1: Do I need special lifting gear?
No. You do not need a forklift or a crane. Two technicians can lift them easily. The casing features strong built-in handles. You place the base plate on the ground. Two workers lift the next module. You stack it on top. The internal plugs align and connect automatically.
Q2: Can I really leave this stacked tower outside in heavy rain?
Yes. The entire assembled stack holds an IP65 rating. The rubber seals block driving rain and blowing dust. Because it uses a cable-free stacking design, all electrical contacts are hidden inside. Water cannot reach the connections. You can install it against an external wall safely. You do not need to build a protective shed.
Q3: Can I put my own company logo on the battery tower?
Yes. We take OEM orders. You can print your logo directly on the metal casing. We customize the shipping boxes too. Custom designs require a Minimum Order Quantity (MOQ). Tell our sales team what you need. We will confirm the exact MOQ and production lead time for you.
