You are correct the batteries limit the charging rate. Did you equalize the 2 batteries or just put them together without doing that. Lead acid batteries are top balanced and lithium bottom balance and both must be equalized. Out of balance batteries will only charge to the highest state of...

There's 3 stages to charging batteries first bulk with highest charging rate 29 volts then absorption lower charging 28 volts then float or trickle charge 27.4 volts. Set float/trickle charge to 27.4 volts Normal for voltage to drop when inverter is used dropping by about 2 volts Try to keep...

I don't know that type of d.i.y solar set up but here is what to check. Solar water heating systems can operate ac or dc water heater elements based on resistance not voltage. The difference is dc power will burn out ac switches not heater elements due to higher heat transfer so you need to...

19-22 volt solar panels are not usually used for a 24 volt solar system because they need more wiring and fitting using twice as many panels. Common mistake with solar beginners because it's seems easy to put a solar system together but the bigger the system the more problems. Your solar array...

You need to understand that dc is lower voltage than ac so higher amps hence higher heat is generated. In my experience it is always best to with any electrical equipment/wiring ac or dc to reduce the maximum recommended operation by 25% for safety and long service life. Dc components in the...

Hi, your solar array needs to be high voltage with high voltage charge controller so a 12 volt system with 12 volt solar panels will not work well over a long distance and generate high amps so thick wiring would be required with maximum 25 amps at mc4 connectors. If you are going to upgrade...

Hi, pv solar water heating works well in the summer months using dump load for free hot water especially on small capacity water tanks and you have a good solar array to do this. This will not work well in the winter months in the UK so I would suggest fitting a heat exchanger coil around the...

Modern buildings now use outside air in ventilation systems to circulate the air/heat/humidity for the vapour control layer around rooms to be able to use heat source pumps efficiently lowering the carbon foot print of the building.

Check heating and ventilation building stats in the construction industry vapour control layer regarding humidity. That's where the facts came from in my posting which also confirm rear outside air intake wood stoves work more efficiently.

For every 10 degrees c of heat the humidity in a room drops by 50% so for a room to stay warm and comfortable it needs to be around 50-60% humidity

Humidity is important it brings heat down from the ceiling keeping the room warmer so increasing humidity increases the temperature.

Wood stoves with outside air intake at the rear pull cold air making the fire work much better and do not pull cold air into the room pushing warm air towards windows and doors increasing room temperature lowering the amount of wood used.

Wood stoves need air to operate so they suck in warm air from the room pulling cold air from the outside via draught in windows/doors.

Not enough information on the monitor it's only showing a 24 volt system charging a battery bank that's at 24.9 volts which is getting close to most you want to drain from the battery bank. However using a juicer for 5 minutes should be o k try not to let the voltage drop below 24 volts that's...

I forgot to mention a 15 ltr dc to dc hot water system is temperature adjustable insulated and will retain heat for 24 hours.

Your water tank capacity is too large for a dc element to be fitted. If you have the roof space 4 x 300watts + half cut cell 35-40 volts solar panels and 600ah + battery storage as a 24 volt system you can run almost everything dc to dc without a dc to ac inverter so less items to go wrong...

I have a holiday riverside leisure spot in France with 4 x 250 panels and tried them in series and parallel in all combinations. They seem to work better in parallel by starting to charge earlier in the morning with the lower voltage and higher amps. I don't have a shading problem in series...

Hi, you need to google enphase iq 3 storage battery it looks like enphase solar sysyem use micro inverters on the solar panels supplying ac power then coupled to the iq 3 storage battery system with built in inverter. You will need an AC coupled battery storage unit like tesla for your AC solar...

Hi, here in the UK off grid reliable bullet proof auto start generator is a Lister. DC voltage down AC wiring to light switch turn on the switch starts generator. Single cylinder Lister with additional piggy backed generator including additional cooling system running house and workshop during...

Hi, you can not connect different size/makes of batteries together in parallel or series because batteries need to equalise to operate correctly in a battery bank cycling up and down evenly. Parallel connection/charging of a 200ah and 100ah will over charge one and under charge the other...

Battery less high input 500 volts DC 48 volt 5 Kw hybrid inverters can operate up to 10 solar panels in series X 2 via a 2 string combiner box that's 20 solar panels producing 5kw. They converter DC to AC directly with no batteries needed during the day and will operate as low as 150 volts DC...

If you are renting out your hut I recommend fitting a LVD to protect the battery bank and combiner box as PV isolator with lightening protection/DC trip to protect the charge controller.

Here in the UK we have low wattage water heaters 800w fitted in motorhomes and caravans and propex low wattage water heaters 8/10 litres on conversions. To use these on solar you need the same size wattage solar array minimum and only turn the water heater on when your battery bank is fully...

I clicked on the link in your thread. You must be in America because that unit is a 60hz cycle 120 volt hybrid unit. The unit can handle up to 145 volts DC input so 2 solar panels can be wired in series and double panels in parallel to the manufacturers maximum solar array input. Hybrid...

Battery capacity depends on temperature the colder it gets below 20c the less ah's are available, also in colder conditions you will have less charging from the solar array. UPS systems general operate via grid charging to maintain battery bank float charge so it has a fully charged battery bank...

Why don't you just fit a twin batteries charge controller that charges the lowest battery automatically.

Hi All, posting to find out how well bifacial panels stand up to the makers claims and if there is any member with them to comment. Any help would be appreciated.

Hi, first how new is your vehicle is it a stop/start model. If so it will be fitted with a battery temperature sensor and smart charging system. Alternator smart charging systems put high amps into the battery up to 80-90 percent then low amps until fully charged regulated by battery...

I reside in the U K in the south west, there is a big difference from north to south for running solar. Solaredge grid systems normally use Mppt tracking optimizers not mini inverters on each high output panel. They operate well in low light and shading plus they turn off not dropping other...

Thank you for the welcome. I have a leisure spot on the river in the Loire Valley with two small caravans. There is no grid power so I have a 24 volt solar system with a large bank of AGM batteries. I run a power board with 24v to 12/13.8v and 5 volt USB via a 60 amp buck converter for 12 volt...

Hi, I am here in the U K not as lucky with good weather for solar systems but here is my experience over many years and now selling systems part time in my retirement. If you are camping off grid we call wild camping a 12 volt system is good for a short period and very reasonable priced. If...

Hi, this may be of interest to you a diy system used here in the u k to heat a greenhouse. The ground material removed to a deepth of 1.5 -2 mtrs then lined with thick insulation material with reflective material as used in the construction industry. Flexiblle s/s extractor hose placed in the...
