No More Guesswork With Inverter Pairing

No More Guesswork With Inverter Pairing

The number one reason off-grid battery installations fail is mismatched communication between the inverter and the battery BMS. This kit eliminates that risk. Each RUiXU module ships with RS485 and Canbus support for over twenty inverter brands — Sol-Ark, Victron, Schneider, Deye, Growatt, and more — configured via DIP address switching. At Off Grid Vault, we pre-vet every system package so every component speaks to every other component. You set the protocol, plug in the cable, and the inverter reads your state of charge, depth of discharge, and health data. No external controller needed, no firmware headaches, no discovering three months later that your battery bank never actually communicated with your inverter.

Fifty Kilowatt-Hours of Off-Grid Proven Storage

Fifty Kilowatt-Hours of Off-Grid Proven Storage

Ten 51.2V, 100Ah LiFePO4 modules deliver 51.2kWh of usable energy in a single rack footprint. At 25 kWh per day consumption — a typical homestead running a well pump, refrigerator, lights, and electronics — this cabinet provides roughly two full days of autonomy with zero solar input. The 10-slot pre-assembled cabinet measures 23.6 inches wide by 29.5 inches deep by 63.4 inches tall, designed to bolt into your utility room or battery enclosure without custom fabrication. Each module weighs 103.6 lb and slides into standard 19-inch rack rails. This is not a portable power station limited to charging phones. This is the backbone of a grid-independent home power architecture built to run for years.

Scale From 50kWh to 160kWh Without Starting Over

Scale From 50kWh to 160kWh Without Starting Over

This RUiXU system supports up to 32 units in parallel — scaling from 5 kWh to 160 kWh without adding an external controller. That means the ten-battery cabinet you install today can become the foundation of a much larger bank as your loads grow. Adding a workshop, a second dwelling, or switching from partial backup to full off-grid operation does not require replacing your inverter or rewiring your architecture. You add batteries, set the DIP address, and the system recognizes the expanded capacity. For homesteaders and preppers planning long-term, this parallel architecture protects your initial investment. You buy once, build incrementally, and never hit a dead end that forces a full system replacement.

Will This Fit Your System?

Verify your space and electrical setup before ordering.

  • Your floor space accommodates a 23.6" x 29.5" footprint
  • Your inverter supports 48V LiFePO4 with RS485 communication
  • Your ceiling available exceeds 63.4" for full cabinet height

“Running a 1,800 sq ft homestead in northern Arizona, I needed a battery bank that could handle my well pump and refrigerator through multi-day winter storms. This RUiXU cabinet was the backbone I was looking for. DIP-switch protocol setup for my Sol-Ark took ten minutes. Two full days of zero-sun autonomy confirmed in real conditions. Off Grid Vault sized the system for my load profile before I pulled the trigger — no guessing, no mismatched components.”

Frequently Asked Questions

At an average residential rate of $250 per month, this 50kWh system pays for itself in roughly three years. After that, the $3,000 per year you were sending to the utility stays in your pocket — indefinitely. This is not a discretionary purchase. It is a fixed-cost energy infrastructure investment with a calculable return. Factor in rate hikes — most utilities have increased rates 30 to 40 percent over the past five years — and the payback window shortens further. You are not spending $9,082. You are redirecting it from the power company to your own property.
Every RUiXU module in this kit supports both Canbus and RS485 communication. Canbus covers Victron, SMA, Sol-Ark, Schneider, Deye, Growatt, Goodwe, and fourteen additional brands. RS485 covers MPP, Voltronic, RCT, and Alpha Outback. You set the inverter protocol using a DIP address switch on the battery — no software flashing, no third-party adapters. Off Grid Vault is an authorized dealer, and we provide a free system design consultation before you purchase. Tell us your inverter model and we confirm the exact protocol and cable configuration. If there is a compatibility issue, we identify it before the system ships.
That depends on your daily consumption. A typical off-grid homestead running a well pump, refrigerator, lighting, and standard electronics consumes 20 to 30 kWh per day. This 50kWh cabinet provides roughly two days of autonomy with zero solar input. If your location receives consistent sun, even winter production will keep the bank cycling within a healthy state of charge range. For larger loads or extended cloudy periods, the system scales to 160 kWh by adding parallel units. Contact our engineering team with your load profile and we will size the exact configuration for your property — no charge.
Lead times vary based on current stock position. This is a substantial system — ten batteries plus a pre-assembled steel cabinet — and it ships via LTL freight at no charge to you. We do not quote fabricated countdowns or artificial stock pressure. Contact us with your zip code and we will provide an accurate delivery estimate based on real inventory and freight routing. For planning purposes, most large battery systems ship within one to three weeks. We will communicate honestly at every stage so you can coordinate your installation timeline.
These are LiFePO4 cells — lithium iron phosphate — not standard lithium-ion. LiFePO4 delivers significantly longer cycle life, better thermal stability, and a much safer failure profile than NMC or LFP-blend chemistries. Each module is rated at 51.2V nominal and 100Ah capacity at 0.2C, with a minimum capacity of 100Ah at the same discharge rate. The rack-mounted design with integrated BMS protects against overcharge, over-discharge, and thermal events. LiFePO4 batteries in stationary storage applications typically deliver 3,000 to 6,000 cycles at 80 percent depth of discharge, translating to ten or more years of daily use in a properly configured system.
The 10-slot cabinet ships pre-assembled. You receive a complete, welded steel enclosure ready to accept the ten battery modules. Each battery slides into a standard rack slot and connects using the included parallel cables and ground cables. The cabinet footprint is 23.6 inches wide by 29.5 inches deep by 63.4 inches tall — compact enough for a utility room, garage, or dedicated battery enclosure. All mounting hardware and cabling is included in the kit. If you need guidance on siting, ventilation, or electrical code compliance, our free system design consultation covers those details before your order ships.
