    The package arrived today, at 5th of May (Less then 3 weeks!). Earlier than announced. The Step Up module power supply works very well! I'm happy! Only a small plastic corner broke off during transport. It does not matter. The packaging was unfortunately not padded enough.

    The form has been delivered in full compliance with the times notified, has been crafted and has not been damaged in the transport. It'a very valid product for various uses: in my case it is used on a solar panel, on 2 beaters for olives.

    It arrived in good time and order. It works well but I think you would need a fan or bigger heatsink if you want to use it above about 300W (depending on input and output conditions). It is a really good tool for testing solar MPPT pump controllers in the field (with only 24V DC available) in bad sun or night conditions.

    This converter is very valid and reliable, I bought a number, the first one has been working for 2 years without giving the slightest disservice. In my case they are used with an output of 36v 5 A and I proceeded to increase the heat sink as the original one with a power of about 200W continuous heats up too much.If you keep the original one you need a small fan. Great material I recommend the purchase. Personal note: in case of failure the repair material is easily purchased.

    This unit is somewhat over - rated.... I would comfortably put 200W through it, but no more than 300W for any medium term... It definitely needs a cooling fan of sorts for any medium term operation above 200W....
