🏡 Will It Work With My System?

The Lithi2-16 works with most 48V hybrid and off-grid inverters, including:

RUiXU SUNON12
RUiXU SUNON7.2
RUiXU RX-12K
Sol-Ark 15K
Other 48V inverters with CAN/RS485 battery comms

📏 Quick check before you order:

Your inverter runs on a 48V battery bank and supports closed-loop battery communication.
You have floor or wall space for each battery. Wall-mounting uses the RX-WMB bracket, sold separately.
Your site can take a freight delivery. Residential and liftgate delivery may add a fee.
A qualified electrician will install and commission the system.

Not sure? Send us your inverter model and loads, and we'll help you pick the right pack size.

Why the Lithi2-16

🔋

16kWh in One Unit

One Lithi2-16 stores as much as three standard 5kWh rack batteries, with fewer connections to make.

🌡️

Self-Heating

A built-in heater warms the cells in cold weather so the battery can keep charging.

📱

Touchscreen Built In

A 5-inch touchscreen on the battery shows status and lets you adjust settings without a laptop.

🔌

Plug & Play Parallel

The included 800A RX9MP busbar has pluggable connectors for up to four batteries, so the bank connects without crimping lugs.

🛞

Easy to Place

Built-in wheels let you roll each battery into position, or wall-mount it with the RX-WMB bracket.

📈

Room to Grow

RUiXU supports up to 32 Lithi2-16 batteries in parallel, so you can keep expanding later.

❓ Common Questions

Why buy a multi-pack instead of single batteries?

You get the RX9MP busbar free, everything ships together, and your batteries arrive matched and ready to parallel.

Can I add more batteries later?

Yes. RUiXU supports up to 32 Lithi2-16 batteries in parallel. The included RX9MP busbar has connectors for up to four.

Can the batteries go outside?

Yes. The Lithi2-16 is RUiXU's outdoor-ready model with self-heating. Your inverter may still need to go indoors, so check its rating.

How is it delivered?

By freight from RUiXU's California warehouse, usually within a few business days of order confirmation. Residential and liftgate delivery may add a fee, and we'll confirm the details before shipping.

Can I install it myself?

We recommend installation by a qualified electrician, and local code usually requires a permit. We're happy to help with system design questions before you buy.
