The LG RESU16H Prime is a 16kWh high-voltage battery built on a 400V architecture — a different design philosophy from the 48V systems that dominate this catalog, and a meaningfully different install.
Why 400V Instead Of 48V
At four hundred volts, the same power moves at roughly one-eighth the current. That means dramatically smaller DC conductors, less resistive loss, faster charging and higher round-trip efficiency. The tradeoff is that high-voltage DC is genuinely dangerous to work on and the ecosystem is closed — this battery pairs with high-voltage hybrid inverters such as the LG SHB-G1, not with the 48V equipment most of this catalog is built around.
Specifications
- Usable energy: 16kWh · 400V high-voltage architecture
- Scalable to 32kWh with two units in parallel
- Advanced lithium-ion chemistry with integrated BMS
- Protection against overheating, overcharging and short circuit
- Indoor or outdoor installation capable
Sixteen Kilowatt-Hours In One Unit
Reaching 16kWh in 48V equipment usually means three or four rack modules, a rack, interconnect cable and a communication bus. This is one enclosure. Fewer connections, less commissioning, and a considerably tidier wall — which is why high-voltage architectures have taken over the professionally installed residential market.
Registration Is Required
LG requires battery registration at installation for warranty coverage. Do it at commissioning, not later — an unregistered unit is a warranty argument waiting to happen.
Plan The Inverter First
This is the part people get wrong. A high-voltage battery is not a drop-in upgrade for a 48V system; the inverter has to match. If you already own 48V equipment, this is not your battery. If you are designing from scratch and want efficiency and a clean install, pair it with the LG SHB-G1. Urban Supply is an authorized LG dealer.

To begin your return, send your order and a receipt or another form of proof of purchase. In order for us to validate your return order right away, please include "RETURN - ORDER #" in the subject line of your message.
If an order is canceled after it has been shipped, the delivery is refused, or it is returned because the customer neglected to make a delivery appointment, it will be automatically sent back to the warehouse and handled as a return.
Please include a brief explanation of the return's cause in the email's body, along with any supporting documentation you deem necessary.
As there is no way for us to track the return package, kindly do not send your purchase back to the manufacturer without first getting in touch with us.
Due to upcoming promotions or lower prices from competing retailers, Order Prices are Final and Cannot Be Refunded.
The sale price is final once an order has been fulfilled.
