説明

The Sun Does Not Deliver a Constant. It Delivers a Signal. Every photovoltaic panel produces a voltage that shifts with cloud cover, panel angle, ambient temperature, and time of day. A PWM controller discards the excess as heat — a crude gatekeeper that treats solar energy like an on/off switch. Maximum Power Point Tracking is different. It is a continuous negotiation between the panel and the battery, sampling voltage and current thousands of times per second to extract every available watt from every available photon. This MPPT solar charge controller operates that negotiation across a 160V DC input range, supporting 12V, 24V, 36V, and 48V battery banks with automatic detection and adaptive charging algorithms optimized for LiFePO4, AGM, Gel, and Flooded lead-acid chemistry.

The controller's parallel-capable architecture allows multiple units to operate on a shared battery bank — each managing its own solar array — for installations that scale from a single 60A residential circuit to a 200A off-grid compound. The integrated RS485 communication port with MODBUS protocol support enables remote monitoring, data logging, and integration with home automation platforms. An LCD display provides real-time data on PV voltage, charging current, battery state of charge, and cumulative energy harvest — but the controller is designed to operate autonomously. Once configured, it manages the entire charge cycle — bulk, absorption, float, and equalization — without human intervention.

Built on a high-efficiency synchronous buck converter topology with a tracking efficiency exceeding 99%, this controller wastes less than 1% of harvested energy in its own operation. The aluminum heatsink chassis dissipates thermal load passively at currents up to 60A; an external fan controller activates for sustained 80A-100A operation in high-ambient environments. Protection circuits cover reverse polarity, over-temperature, over-voltage, short-circuit, and PV reverse-current — each fault condition triggers a logged event and automatic recovery once the condition clears.

Energy independence is not a product you buy. It is a system you build — and the charge controller is its intelligence.


Key Features

  • ✦ 160V DC Maximum PV Input: Support for high-voltage series string configurations — fewer parallel strings, thinner gauge wiring, lower installation cost. Compatible with 12V/24V/36V/48V battery systems with automatic voltage detection.
  • ✦ >99% MPPT Tracking Efficiency: Synchronous buck converter with real-time impedance matching. The controller samples the I-V curve continuously and locks onto the maximum power point within 0.1V precision.
  • ✦ Multi-Chemistry Adaptive Charging: Preset charge profiles for LiFePO4 (3.65V/cell), AGM, Gel, Flooded Lead-Acid, and user-defined custom parameters. Temperature-compensated voltage regulation with external sensor input.
  • ✦ Parallel-Ready Architecture: Deploy multiple controllers on a shared battery bank — each managing its own array. Scale from 60A (1 unit) to 200A (4 units) without communication conflicts.
  • ✦ RS485 / MODBUS Communication: Remote monitoring, data logging, and automation integration via standard industrial protocol. Compatible with Home Assistant, Node-RED, and custom SCADA implementations.
  • ✦ Comprehensive Protection Suite: Reverse polarity (PV and battery), over-voltage, over-temperature, short-circuit, and PV reverse-current protection. Auto-recovery with fault logging on every channel.
  • ✦ Passive Cooling + Active Fan Support: Aluminum heatsink chassis handles continuous 60A passively. Built-in fan controller activates at configurable temperature thresholds for sustained 80A-100A operation in high-ambient environments.

Application Scenarios

Ideal for off-grid residential solar systems, RV and marine auxiliary power, remote telecom and monitoring stations, agricultural water-pump installations, and hybrid grid-tie systems with battery backup. The 160V PV input voltage ceiling allows series string configurations that reduce cable gauge requirements on long panel-to-controller runs — particularly valuable for ground-mount arrays located 50+ meters from the battery bank. The MODBUS RS485 interface enables integration with home energy management platforms for users who want centralized monitoring of solar harvest, battery state, and load consumption on a single dashboard. Multi-unit parallel configurations are well-suited for containerized off-grid systems where redundant charge controllers increase system reliability.

Frequently Asked Questions

Q: Can I connect solar panels in series to exceed 160V?

A: No. The 160V DC maximum PV input voltage is a hard limit measured as open-circuit voltage (Voc) at the lowest expected temperature. In cold weather, panel voltage increases — a serial string with a nominal 140V Voc at 25°C may exceed 160V at -10°C and damage the controller. Always calculate Voc at your local minimum temperature and add a 10% safety margin. For panels with a temperature coefficient of -0.3%/°C, keep the nominal Voc below 145V in moderate climates and below 135V in cold climates.

Q: Does this work with LiFePO4 batteries that have an internal BMS?

A: Yes. The controller includes a dedicated LiFePO4 charging profile with configurable absorption (3.65V/cell) and float (3.40V/cell) voltages. The battery's internal BMS handles cell-level balancing and disconnect protection independently — the charge controller manages the bulk/absorption/float phases at the pack level. For batteries with communication-capable BMS (CAN/RS485), the controller's MODBUS interface can integrate with third-party monitoring platforms for pack-level visibility.

Q: Can I run multiple controllers in parallel on the same battery bank?

A: Yes. The controller supports parallel operation — connect multiple units to a shared battery bank, each with its own independent PV array. There is no master/slave configuration required; each controller manages its own charge cycle independently. For a 200A system, deploy four 60A controllers (or three 80A) with separate array strings. Ensure all controllers share the same battery voltage setting and charge parameters.

Q: What monitoring options are available?

A: The built-in backlit LCD displays real-time PV voltage, charging current, battery voltage, state of charge, and cumulative energy harvest. The RS485 port with MODBUS RTU protocol enables wired connection to monitoring platforms (Home Assistant, Victron Cerbo GX with MODBUS plugin, custom Python/Node-RED implementations). An optional Bluetooth module provides wireless access via a mobile app for configuration and live data viewing within a 10-meter range.

Q: What happens if the battery is disconnected while the panels are producing power?

A: The controller has PV reverse-current protection — if the battery is disconnected, the controller immediately stops drawing current from the panels. However, you should never disconnect the battery while the system is operating. Always disconnect PV first, then battery. When reconnecting, connect battery first (so the controller powers up and detects the system voltage), then connect PV. This sequence is standard for all solar charge controllers.

Parallel operation works flawlessly

Running two 60A controllers on a shared 48V 200Ah LiFePO4 bank — each with its own 2kW array. No communication conflicts, no master/slave setup needed. Each controller manages its own charge cycle independently. Total system output peaks at 5.6kW on clear summer days.

Efficient, but the fan kicks in louder than expected

The MPPT tracking is excellent — I am seeing 97%+ on the display under direct sun. The LiFePO4 charge profile was pre-configured and matched my battery specs exactly. Only complaint: the cooling fan on the 100A model is noticeable in a quiet RV interior. I mounted it in the pass-through compartment to solve that.

Running my off-grid cabin for three months now

Installed the 80A version with 6 x 400W panels in a 2S3P configuration. The 160V PV input ceiling let me run series pairs without oversized cable. The MODBUS monitoring via Home Assistant gives me a real-time dashboard of charge current and battery SOC.
