Some of the heads of auto companies were questioned on how much CO2 was in the atmosphere: they all said it was 5% or over. They have no idea what is going on. 'Climate change' is an obvious scam, look at CO2 coalition org, or Watts Up With That, Climate Depot, etc. I have solar power...

I just read this daft article from the BBC: https://www.bbc.co.uk/news/science-environment-65602519 Solar panels don't have a life of only 25 to 30 years. They will still work, except they will have lost some of their efficiency and may 'only' be giving out 80% or maybe even only 70% of their...

I can buy two 5.6kW Anenji inverters with a two year guarantee from Germany for about £900 after paying import duty...

My three Pylontech US5000s were down to 11C a few weeks ago, because the outside temperature was around zero centigrade, so I bought a £20 hot water cylinder jacket from Toolstation (UK DIY shop) - it comes with four pieces of insulated jacket - and fitted two parts of it around the batteries...

Hi, I am trying to remove the two green connectors that each have a black and red cable coming out of them, from one of my MPP Solar PIP5048MKX inverters, so that I can fit the replacement MPPT board they sent me yesterday (it only took one week from Taiwan, pretty amazing seeing as it was over...

I have two 6kW PV strings, and two 5kW inverters running in parallel, and I was thinking about buying a third inverter to run in parallel, to a) reduce the total load on each inverter, and b) allow me to use over 10kW at one time in the house if I need to. I don't want to have to dig up my...

I have just set up my first solar system, 12kW using 20 x Canadian Solar 595W panels, two MPP Solar PIP5048MKX inverters in parallel, and two Pylontech US5000 batteries (10kWh in total). I have been using the system for three or four weeks. My girlfriend and I built a ground mount using ground...

I've just discovered that Deye make a microinverter, which I believe is mounted on the back of each solar panel, and changes its output to AC. But the price for one microinverter is much more than one of my (very large) 595W solar panels cost, at £358...

I am still having problems with my two 4.8kWh Pylontech US5000 batteries not charging more than halfway, after allegedly receiving 12kWh of power from my two MPP Solar inverters. In September, when I first set my solar system up, I was getting 25kWh per day from the solar panels, and the...

I am hoping to have a Deye 8kW inverter installed soon, to replace my two MPP Solar PIP5048MKX. I have three Pylontech US5000 batteries, which are connected to the two MPP Solar inverters by the standard Pylontech 100A cables (I believe they are 25mm). Two cables come one inverter to the first...

I have been looking into Tigo TS4-A-0 optimisers, because during the Winter months my 12kW array has a lot of shadows as two of my neighbours to the South of my garden each have two huge trees in their gardens, two of which are evergreens, so there is a lot of shade across my panels in December...

My 12kW of ground mounted Canadian Solar 595W panels don't give out enough kWh to get me through a day during the Winter months, if it's a cloudy day. I was thinking of buying another 8kW of panels (you can now buy 8kW of new solar panels from BimbleSolar for £1,200 plus delivery) to use with a...

I have been reading up about bypass diodes, and I noticed that the guarantee for my Canadian Solar panels states that they mustn't be in shade for more than 100 hours, or something like that, and I have a large tree that is currently shading my panels for several hours of the day, which I am...

I am thinking of buying two Voltacon Conversol V7 5kW off grid inverters, which are incapable of exporting to the grid. Can I legally use them without getting DNO approval? They don't have a G99 certificate. The same question applies to my existing MPP Solar PIP5048MKX inverters.

I am just setting up a pipe to go along the wall about 6 feet into my house, to my electricity meter, through which I am going to be putting meter tails for my electrician to fit to the inverter and grid input. While I'm doing this, I was thinking of putting a length of two core cable through...

My electrician is installing my Voltacon 5kW inverters in a new shed I built for them - does it matter that the 70mm cables shown are different lengths? Or are they so thick that the resistance difference won't affect the voltage that each inverter sees from the three Pylontech US5000 batteries...

Has anybody got any experience with the Anenji inverters that are on sale on Ebay UK? After my less than good experience with MPP Solar, whose auctions keep saying how other companies' inverters aren't as good quality as theirs (which I don't believe is true), I wonder if these Anenji inverters...

I am planning on getting a Sunsynk Ecco 8kW Hybrid Inverter - if the grid goes down, does the inverter stop providing power to the house? (I have three Pylontech US5000 batteries.)

I have just found out that Octopus Energy in the U.K. are now paying 24p/kWh for exported electricity from residential customers with solar panels, a vast increase over the 7p (I think) that they initially offered for SEG (Smart Export Guarantee) export. As I have 12kW of solar panels and can...

Hi, I use MultiSIBControl with my two MPP Solar PIP5048MKX inverters, and three Pylontech US5000 batteries. I use a 15m Ethernet cable to connect the Console port of my master battery to my Windows 10 PC, (not my main PC, which is Windows 8.1), but I keep getting errors in the battery data, such...

Hi, I am looking to replace my faulty MPP Solar PIP5048MKX inverters with either two Growatt SPF5000ES (which cannot export to the grid), or a Deye 8kW Hybrid Inverter (which can export to the grid, but this function can be turned off in the settings). Do I need to apply for a G99 (or similar)...

Hi, I have an AIRFORCE 16,000BTU SPLIT mobile air conditioner, and sometimes my 2 x 5kW Voltacon Conversol v7 inverters overload when (I think) the compressor in the air conditioner is starting up, or maybe turning off. (I can't be sure because I only notice it happening when the air conditioner...

I am about to buy a Sunsynk inverter and get it installed by an MCS certified electrician. The electrician told me that I won't need a transfer switch, because the Sunsynk inverters don't need them, and will supply power to the house due to the 'anti islanding' function - but I want the transfer...

I have 12kW of solar panels, and next Summer I expect them to be making at least 50kWh per day, possibly 80kWh. I only need maybe 15kWh per day in the Summer (I will be running two mini split air conditioners as often as needed, but that's only something like 2-3kW and maybe 10-20kWh per day?)...

I have done a simple wiring diagram for what I think I need for my set up of two Voltacon V7 5kW inverters, with 2 strings of 6kW of solar panels, and 3 Pylontech US5000 batteries - does this look correct to you guys? I am have been trying to find an electrician to install this wiring, etc. for...

I can't find any discussions here about how people with multiple inverters are splitting their incoming AC into two (or more), and combining their outgoing AC from two or more into one output. I presume you normally use a distribution block like this...

Hi, I have two strings of 10 x 595W Canadian Solar solar panels, giving just under 12kW. I am thinking about buying an 8.8kW Sunsynk Hybrid inverter. The Canadian Solar Voc is 41.1V, and the Sunsynk inverter can take PV input of up to 500V - so since 10 x 41.1V is 411V, shouldn't they work fine...

So after the developer of MultiSibControl told me not to connect my batteries' data cable to my MPP Solar PIP5048MKX inverters, and not to use the 'Pyl' setting, because they charge at too high a voltage, I changed the setting to 'Usr' and set the voltages to: Bulk charge 52.5V Bulk Float...

Is there an electronic device that you can plug into a non-export capable inverter, in order to export to the grid?

Hi, I have two MPP Solar PIP5048MKX inverters, and have connected them to a Raspberry Pi running Solar Assistant, each inverter has its own USB cable connected to the Raspberry Pi (admittedly by 15m of 'active' USB extension cables). Solar Assistant says that only one of the inverters is...
