Review: Very easy to use, great product
Review: This review is for Tracer4210AN. I had thought that 24v panels would charge my 24v panels. This is incorrect. I reached out to Epever support and they informed me I must supply 34v to charge 24v batteries. Thankfully I have two of the panels and moved from parallel to series and it's charging the batteries great. Looking at the panel voltage and the battery voltage and controller parameters, I'm not certain there's ever an ideal setup without lots of lower voltage panels where one can get the perfect pairing for the least loss, however in lower light I should still be supplying enough voltage to charge - not certain on amperage, time will tell.

## Features

- Negative Grounding MPPT Solar Charge Controller Tracer4210AN, The advanced MPPT control algorithm makes this 10 amp MPPT controller tracking efficiency higher than 99.5%.
- Built-in LCD screen displays key charging parameters. Multiple connectivity options for the controller (remote meter, mobile app, PC software etc) enable the user to personalise each charging stage, create a user-defined battery type with specific parameters and access exclusive settings.
- Compatibility with multiple battery types for convenient use, support Sealed lead acid, gel, flooded, lithium and users. Suitable for solar panels up to 520W (12V battery or battery bank) or 1040W (24V system). Current limiting function (10A) allows possibility of adding more solar panels in the future.
- RS-485 communication bus interface and Modbus communication protocol, available to meet various communication requirements in different situations.
- With Modbus communication protocol interface, full-load operation without any drop in capacity within the range of working environment temperature, it is convenient for customers to expand applications and monitor in various fields like telecommunication base station, household system, street lighting system, wilderness monitoring system, etc.

*by G***N on 12 May 2024*

I connected this to 4 flexible monocrystalline panels rated 100 watts each. Panels wired in 2 parallel sets, then series connected the 2 pairs for open circuit voltage around 45 volts. I am using a size 8D flooded lead-acid battery with about 200 amp-hours of capacity and 12 volts. The primary load is a Xantrex 3kW sine wave inverter. I was getting 125 watts solar charging in the 4pm late afternoon sun with the panels mostly flat and two panels shaded. Controller came in a kit with the remote, which I highly recommend. I only needed the manual for a minute at first, then everything in the setup was intuitive. This seems like a rugged, well built piece of electronic hardware. I will update this review if anything goes wrong, but initial functionality looks great.
