Is anyone having problems with hf / vhf radio interference (rfi)?

On MPPT and PMI controllers of different brands, RFI particularly in the VHF & UHF bands can be extreme. The solar panels do act as large antennas transmitting the interference. Some fairly simple decoupling circuitry can help. Right at the PV input, i've used a large forward diode into a large, CPU-grade electrolytic along with common-mode chokes on wiring before the diode. On the controller outputs, a "Corcom" type pi-filter helps a lot, but components in series with the output must accept full output current without much voltage drop. This can get rid of about 99% of RFI without too much problem. I do use solar and wind turbines for power at my off-grid property and run amateur radio equipment from 70 cm to 160 meter bands.

What does "rated battery current" mean? Does the load current change with each different model?

The rated current is 20Apeak If you want to connect to inverter that draw more than 20amp Use relay to switch load Connect relay coil to Rover load output

What is the max available amps to the load terminals?

I never put loads directly on the controller. I only put loads on the battery terminals.

I have a: itehil solar panel, 100w 18v monocrystalline portable solar panel, high efficiency waterproof solar panel. can i use it with this controler?

Sure, but get a Victron instead. This is an antique. 😉
