Solar Battery Storage Compatible Inverter List — Rakour LV & HV Series

Connecting a solar battery storage system to an incompatible inverter causes more than poor performance. Incorrect voltage alignment forces the inverter into fault mode, triggering BMS protection shutdowns. In the worst cases, repeated forced shutdowns accelerate cell degradation, reduce total cycle life, and can void your product warranty entirely.

True compatibility depends on three technical layers: DC voltage range, battery chemistry charge profile, and communication protocol support. Rakour LiFePO4 batteries operate at 46.4–57.6V (LV) or up to 979.2V (HV). Your inverter must accept that specific voltage range and support CAN bus or RS485 for closed-loop BMS data exchange.

Many manufacturers list inverter brands without specifying protocol type or tested firmware versions. Rakour only publishes inverter models that have completed hands-on communication handshake testing — meaning BMS data exchange between battery and inverter has been physically verified on the bench, not simply assumed from a datasheet comparison.

Every inverter candidate is benchmarked against Rakour's full product range. DC input voltage, maximum charge/discharge current — up to 100A for HV models — and rated power output are all cross-checked to ensure the inverter operates safely across the complete SOC range of our solar battery storage units under real load conditions.

Rakour engineers establish a live CAN or RS485 link between the battery BCU and the inverter BMS port. The test confirms that charge current commands, discharge cut-off voltage, cell temperature, and SOC percentage are accurately transmitted and acted upon by both sides. No missing or mismatched data fields are accepted for the listing.

For systems using multiple Rakour units in parallel, the full stack is tested as a group. Engineers verify address assignment, inter-battery RS485-2 communication, and inverter response under dynamic load transitions, ensuring the battery inverter pairing stays stable at full rated power output.

Rakour's LV rack batteries — including 100Ah, 200Ah, 280Ah, and 314Ah models — are designed for hybrid solar inverters operating in the 48V DC range. Verified compatible brands include Deye, Growatt, Solis, GoodWe, Victron, Luxpower, SolaX, and Sofar. Both CAN bus and RS485 connections are supported, selectable directly from the battery's built-in touchscreen without rewiring.

The HV series (200Ah and 314Ah) connects to high-voltage inverters from Deye (SUN-29.9K to SUN-80K), with a dedicated BCU managing up to 17 stacked modules. The BCU CAN port links directly to the inverter's BMS1 terminal, enabling full closed-loop control. The HV series includes a soft-start circuit supporting inverters that lack built-in inrush protection.

Each table entry shows: battery model, inverter brand and model number, connection protocol (CAN/RS485), and loop type (open or closed). Closed-loop entries mean the inverter actively reads BMS data. Open-loop entries require manual parameter input on the inverter side before commissioning.

Through CAN bus or RS485, Rakour's BMS battery management system transmits six live parameters: cell voltage, pack voltage, current, state of charge, temperature, and fault codes. The inverter uses this data to dynamically adjust charge voltage and discharge cut-off limits — not fixed presets. This is what real closed-loop communication looks like.

CAN bus communicates at up to 500 kbps and handles multi-node environments without signal degradation. Rakour's BCU uses the RJ45 CAN port (PIN4: CAN-H, PIN5: CAN-L) to connect to the inverter BMS1 port. Deye SUN-29.9K–80K inverters use this channel by default, making CAN bus the recommended protocol for all HV pairings.

RS485 supports longer cable runs and is available on virtually all hybrid inverters for solar. On Rakour LV batteries, the RS485-1/CAN port handles inverter communication, while RS485-2 is reserved for inter-battery parallel data. The built-in touchscreen lets installers switch protocol per brand without any rewiring required.

The choice between a low voltage battery and a high voltage system depends on your inverter's DC input range and total power requirement. Rakour LV batteries operate at 46.4–57.6V, pairing with standard 48V inverters up to 16 kW per unit. This makes them the default choice for most residential solar-plus-storage installations.

Rakour's high voltage battery series runs from 185.6V to 979.2V, reducing DC cable losses and supporting large inverters such as Deye SUN-29.9K to SUN-80K. Fewer parallel strings mean simpler wiring, lower connector current stress, and better round-trip efficiency at commercial-scale deployments above 30 kW.

LV units support up to 15 batteries in parallel per system; HV units stack 5 to 17 modules in series inside one BCU enclosure. Both series are fully rack-mountable. Rakour's modular architecture allows installers to begin at a smaller capacity and expand later without replacing the inverter or rewiring communication cables.

Rakour LV batteries support up to 15 units in parallel battery configuration. Before connecting, confirm the voltage difference between units is within 1V and production dates are within 12 months. The host battery (ADDR = 1000) connects to the inverter; slave units are addressed sequentially using the RS485-2 inter-battery port.

Each BAT port on dual-input Deye inverters is limited to 50A. For batteries in parallel with 10 kWh capacity and 100A discharge rating, Rakour recommends connecting BCU P1+/P1– to BAT1 and P2+/P2– to BAT2. This parallel shunt doubles effective current without requiring a second battery string.

To prevent uneven discharge across parallel units, use staggered terminal wiring: upper-left positive to lower-right negative at the inverter DC terminals, or the reverse diagonal. This cross-connection forces equal current across the stack and is mandatory for any multi-unit battery parallel connection to maintain long-term capacity balance.

For HV systems, connect BCU P1+ and P1– to inverter BAT1 terminals, then P2+ and P2– to BAT2. For LV parallel setups, stagger terminals across units before connecting to the inverter. Confirm polarity before powering on and use rated cable cross-section to prevent voltage drop at full discharge current.

Connect the BCU or host battery CAN port to the inverter BMS1 port using the supplied RJ45 cable. For LV multi-unit stacks, link modules sequentially via RS485-2. Set each unit DIP switch: host at address 1, slaves from 2 to 15. Verify address sequence before enabling the inverter.

Set battery mode to Lithium on the inverter and enable Parallel bat1 and bat2 when using dual BAT ports. Do not manually enter a fixed charge voltage. Rakour's BMS pushes dynamic limits via CAN, and manual overrides conflict with parallel battery wiring balance control, potentially triggering BMS shutdowns.

All Rakour lithium battery storage products carry CE, MSDS, and UN38.3 certification. LV models such as the 51.2V200Ah-LV additionally hold IEC62619 and ROHS approvals. These certifications confirm that cell chemistry, BMS protection design, and transportation safety have each been independently tested, not self-declared by the manufacturer.

Rakour's BMS provides six hardware-level protections: overcharge, over-discharge, over-current, short circuit, high temperature, and low temperature cutoff. For the HV series, the BCU adds a DC fuse and soft-start circuit to prevent inrush damage at inverter startup. These protections work independently of the inverter firmware version.

All Rakour batteries carry a 5-year warranty. To maintain coverage, the system must stay within documented voltage and current limits, and the paired inverter must appear on Rakour's verified compatibility list. Connecting to an unlisted inverter or bypassing BMS communication voids the warranty, as safe boundaries cannot be enforced.
