Product information

Description

ST-401 NPWM by No name is a solar charge controller in a white enclosure designed to manage photovoltaic installations. The ST-401 NPWM provides charge regulation and essential protection functions to connect solar panels to battery systems, prevent overcharge and ensure stable charging for small to medium off-grid or hybrid solar setups. The compact white casing and straightforward interface make it suitable for residential and light commercial applications where reliable battery charging and system protection are required.

Advantages

The controller integrates NPWM regulation technology to optimize charging efficiency and reduce energy losses during battery recharge. Built-in protection features guard against overcharge, reverse polarity and short circuits, contributing to longer battery life and safer operation. Its compact white enclosure allows flexible mounting in equipment cabinets or small enclosures while maintaining a low visual profile. The design supports easy wiring and basic monitoring without requiring complex configuration.

Suitable for

  • Small off-grid solar systems for cabins and remote lighting
  • Residential solar setups with battery storage
  • Hybrid systems that combine grid and solar inputs for backup power
  • Portable or temporary photovoltaic installations for events or field work

Key specifications

  • Controller type: NPWM solar charge controller for battery charging
  • Casing color and material: white enclosure designed for indoor mounting
  • Functions: charge regulation, overcharge protection, reverse polarity protection, short-circuit protection
  • Application: compatible with photovoltaic panels and lead‑acid or similar battery systems commonly used in off-grid installations
  • Installation: wall or panel mounting with standard electrical terminals for solar panel and battery connections

How to use

Install the ST-401 NPWM on a stable indoor surface away from direct moisture and excessive heat. Connect the battery first, observing correct polarity, then connect the photovoltaic panel array to the controller input. Ensure wiring is sized appropriately for the expected current and that fuses or circuit breakers are installed as required by local electrical regulations. After powering, check the controller indicators or basic display to confirm charging status and that no protection alarms are active. Routine visual inspections of connections and battery condition are recommended to maintain reliable operation.

Usage recommendations

Use the controller with batteries and solar panels that match the controller's voltage range and rated current. Protect wiring with correctly rated fuses or breakers, and place the device indoors or inside a weatherproof enclosure if used in exposed locations. Periodically inspect terminals for corrosion and confirm battery electrolyte levels where applicable. For systems with sensitive loads, consider adding appropriate load protection or surge suppression upstream.
