ECO-N-T — PWM charge controller 10–20 A
Country: Germany · Model: ECO-N-T
Potted electronics and the absence of any settings distinguish the ECO-N-T, a 10 or 20 A PWM charge controller for small 12 or 24 V solar systems. It is installed in solar home systems, signal lights and remote sensors where the equipment is mounted by non-specialists.

Description
The board is fully potted, so the enclosure is rated IP68 and is not afraid of moisture, vibration and condensation. The terminals, however, are protected only to IP21, so the connection point is kept dry, in a box or under a cover. The controller is designed for lead-acid batteries of the gel, AGM and flooded types and does not serve lithium batteries. It detects 12 or 24 V automatically, and the PV input allows 30 or 50 V. Programming is not provided, and the charging parameters are set at the factory. UL1741 and Class I Div. 2 certification opens the way to industrial facilities with strict safety requirements.
How to choose
The choice comes down to the current, 10 or 20 A, and this rating must exceed the short-circuit current of the modules with a margin. Lithium batteries need a different controller, for example the MPPT model CX-N-MPPT (30 or 60 A). If you want to see the charge level on a display and have a USB output, take the CXNup (10–40 A), although its enclosure is only IP22. When the array is no larger than 500 W and every percent of efficiency counts, the ECO-N-MPPT 85/15 is the logical choice.

FAQ
Does the ECO-N-T work with lithium batteries?
No, the controller is designed for lead-acid batteries of the gel, AGM and flooded types. For lithium batteries, choose a model with a suitable charge profile.
Can the charge settings in the ECO-N-T be changed?
No, programming is not provided and the charging algorithm is fixed. The controller recognizes the 12 or 24 V system voltage by itself.
How well is the ECO-N-T protected against moisture?
The potted enclosure is IP68 and the terminals are IP21. So the connections are placed in a dry spot or closed with a cover.
What solar panel voltage does the ECO-N-T withstand?
The PV input is rated 30 or 50 V. The string is built so that the open-circuit voltage does not exceed this limit even in frost.
What certificates does the ECO-N-T controller have?
It is certified to UL1741 and Class I Div. 2, which matters for industrial and oil and gas facilities.
