Hi all, I'm fixed on getting a Huawei solar sun 2000, 3kw model. I was looking at 6 X JA 550 watt panels at 3360 watts total but noticed their max current is 13.3 amps whereas the inverter states a max current of 12.5amps. Is this going to be a major problem. I live in the Costa blanca and my...

Hi, I'm planning on using one of the above inverters but am concerned about their hum noise. Both are fanless, and I just wondered which has the lowest noise. The ideal location for an inverter is on my patio which is open to the front but has a brick and concrete ceiling and walls adjoining...

Ive finally realised that my east west roof set up will only need one mppt input inverter. My west roof will take about 4kw but the smaller east roof will only take two panels without shading problems. I've been looking at two input inverters when just a one input would suffice. My question is...

I'm going to have 8 panels ja solar 460 watts installed on my roof and can have the 3 kw or 4 kw Huawei inverter for the same price. The total pc input could be 8 X 460 =3680 watts. I know inverters will handle more pv than their rated kilowatts but which would you advise me getting? I don't...

Hi, I knew I should have ordered a spare battery when I ordered 8 cells from Docen, who I recommend . On the initial charge I set the charger at night and set the volt too high, result bloated battery in the morning. Am finding it difficult to buy from China as most sell in batches of 4 or more...

Can I use a series string of 4 panels with end panel at 90 degrees to the first 3 panels, like a L shape.

Hi All, A simple question, my intended inverter has a maximum pv voltage of 100 volts and I think that havings strings of 48v (90v o/c) would be better than having strings of 24v (45v (o/c). Does anyone know how much efficient a higher voltage would have over a lower voltage. I have some...

Hi first post, I couldn't find a new member forum so hope its ok diving straight in. Im planning an off grid system that will reduce my bill by some 80%, my average daily wattage use is 10kwatts. I have a shallow east west roof and am considering buying a Must, 3000w-24v-mppt-50a with max...
