Simtek ECO Series – DC King-70A MPPT Solar Charge Controller – 110 VOC, 70A | 12V/24V | Dual Display | Low Battery Load Cutoff | Works with & without Battery

The Simtek ECO Series DC King-70A MPPT Solar Charge Controller is a high-efficiency solar charge controller engineered to maximize the performance of your solar energy system at an economical price. Built with advanced Maximum Power Point Tracking (MPPT) technology, this controller intelligently extracts the most usable power from your solar panels, increasing energy yield while reducing charging losses.

Designed for flexibility, reliability, and ease of use, it supports both 12V and 24V battery systems with automatic voltage detection and features a 110 V open-circuit voltage (VOC) input capability and 70 A charging current, making it suitable for medium to large residential, commercial, or off-grid solar setups.

Key features include:

🔌 Advanced MPPT Tracking
• Optimizes solar panel output for faster and more efficient charging compared to traditional PWM controllers.

⚡ High-Capacity Output
• 70 A charging current with up to 110 V VOC input, supporting 12 V/24 V systems seamlessly.

🔋 Works With or Without Battery
• Can power DC loads directly (up to ~50 A) even without a battery connected — ideal for daytime PV load operation.

📊 Dual Display
• LED + digital display shows real-time system data including voltage, current, battery status, and performance metrics.

🛡️ Battery Protection & Safety Features
• Includes low-battery load cutoff to prevent deep discharge, overcharge protection, overcurrent safety, thermal shutdown, and reverse polarity protection for enhanced system safety.

⚙️ Automatic 12V/24V Detection
• Automatically detects the system voltage and configures charging parameters accordingly without manual switching.

📦 Easy Setup & Reliability
• Simple plug-and-play installation with broad battery compatibility (lead-acid, GEL, AGM, lithium, etc.) and backed by a manufacturer warranty (typically 6 months depending on the seller).

Why Choose This Controller?
Ideal for users who want efficient solar power management without breaking the bank, the Simtek DC King-70A offers smart energy harvesting, robust protections, and versatile operation — whether used in standalone DC load systems or paired with batteries for full solar storage solutions.
