MPPT Solar Charge Controller BlueSolar 150/35 — 150V PV input, 35A charge current

BlueSolar MPPT 150/35 is an MPPT solar charge controller designed to maximize energy harvest from photovoltaic (PV) arrays with a maximum PV input voltage of 150 V and a continuous charge current rating of 35 A. The controller performs maximum power point tracking to optimize panel output under varying irradiance and temperature, manages battery charging stages to maintain battery health, and includes protections such as overcharge prevention and reverse polarity protection. Suitable for off-grid and hybrid systems, this unit supports multiple battery chemistries and is intended for reliable battery maintenance and improved overall system efficiency.

Advantages

The BlueSolar MPPT 150/35 improves conversion efficiency compared with conventional PWM controllers by tracking the PV array’s maximum power point and adjusting charging accordingly. Its 150 V PV input allows use with higher-voltage PV strings or larger panel arrays, reducing wiring losses and enabling longer cable runs. Built-in protections safeguard batteries and connected equipment from overcharging, reverse polarity and short-circuit conditions, while the 35 A continuous output supports mid-sized battery banks for residential and small commercial installations.

Suitable for

• Off-grid solar systems for cabins, RVs and remote buildings
• Hybrid solar-battery installations with inverter-charger setups
• Residential PV arrays where higher PV open-circuit voltage is required
• Battery charging for lead‑acid, AGM, gel and compatible lithium battery systems (as supported by the system)

Key specifications

• Maximum PV input voltage: 150 V
• Continuous charge current: 35 A
• MPPT technology for optimized panel power extraction
• Multi-stage charging to support battery health and longevity
• Protections: overcharge protection, reverse polarity protection, short-circuit protection
• Suitable for use with common battery chemistries when configured correctly

How to use

Install the controller according to local electrical codes and the manufacturer’s mounting and ventilation guidelines, ensuring correct orientation and clearance for heat dissipation. Connect the battery first, then the PV array, observing correct polarity and verifying that PV open-circuit voltage and array configuration do not exceed 150 V. Configure the controller’s charging parameters for the battery type in use and verify operating status via the built-in indicators or compatible monitoring interface. Regularly inspect electrical connections and keep the unit free of dust and debris to maintain performance.

Recommendations

For best results, match the PV array voltage to the controller’s MPPT operating range and size the battery and wiring to handle the 35 A continuous charge current. Use appropriately rated fuses or circuit breakers on the PV and battery circuits, follow safety practices during installation, and consult product documentation for detailed configuration settings and compatible battery types.
