I am connecting a sub panel to my house mainly because my main breaker box is full. It will also make it easier to work with while expanding. I plan on moving a 15 amp circuit to it one at a time and see what and how long it will run. A bed room does not consume that much power for example at...

From what I can tell a battery tender is something you hook to the battery and leave hooked up while it constantly maintains the battery? I did not think you would want a battery charger or tender connected to your battery while it is connected to your system. I have always disconnected the...

I just received the parts from Amazon today. Can you tell me if the pin connections are straight through? Maybe send a picture of how the connector connects to the USB adapter? With 1 USB connector and 1 cable connected to it does it matter which Valence cable you connect to? You do disconnect...

Let me do some further testing...

I still cannot get the laptop to find the battery. I am logged in as administrator on Windows 10. I connect to the battery and start the scan and it will not find any modules any ideas. I have a picture of the adapter wiring 5 wires straight through.

While on the phone with Renogy I thought about a PWM vs. MPPT question. Their 200 and 400 watt kits come with a Wanderer PWM controller and not a MPPT. This is the reason they stated. If you only have say 4 panels and maybe a couple batteries the MPPT does not really make a difference. Even...

I cannot find the thread when I asked about minimum charge rate on a Vmax 125 ah. The sticker on the battery says 14.7 recommended 14.5 v maximum charge. What should I set the PWM and the ATS at for minimum charge? Right now it has been cloudy for a few days and some rain. I am using a older...

I have read a bunch lately. I came across an article in the last couple days about battery discharge rates. It said an AGM battery can be discharged to about 75% to be safe. A lithium battery can be completely discharged or 20% to be safe. Does this mean that a 100 ah Lithium battery such as...

I recently purchased 2 Valence 138 ah batteries with 300 or less cycles that were used in electric vehicles. I have both in parallel and use a 4 amp battery tender connected. When charged they go to either 14.5 or 14.7 and then slowly drop to 13.38 which I have verified correct. Green lights...

I am considering going to a 24 volt All in One system. I currently have a Vmax Tank 125 amp battery which is $280.00. The only source I have for batteries for solar use is Amazon and what I have seen in the videos. If you know of other sources for batteries and batteries you have had good...

Valence u-charge RT Series U1-12RT Lithium Iron Magnesium Phosphate Battery I did not see the ah rating on the battery. I understand these are used in Medical Equipment. Can you tell from the model number if these are 12v 100 amp batteries? Is this a good deal on a Valence Battery 349.00...

Can you put Anderson connectors on 10 gauge PV Wire instead of MC4 Can you put Anderson connectors on the 12 gauge speaker wire Will recommends on his site. Hope both ways will work well. The mfg said you could use speaker wire permanently outdoors????

I kept wondering why anyone would really want 220v unit. Then I thought you could plug it into a breaker box like the main breaker box in your house but still use it for 110 V circuits in this correct? Or someone could get a whole lot of battery power and run their dryer but I did not think this...

I know with batteries you need to use the same ones in a bank. However, with solar panels does it matter? I have 2 Nature Power 165 watt batteries now. I want to add 2 100 watt panels is this ok? The panels came with SAE connectors on them and I purchased a SAE Y to MC4 adapter and connected...

On a 24 volt system can you only have 2 batteries? I know the batteries are put in series but can you add more since the 2 batteries are in series is 24v? can you have 3 batteries or would you have 4 batteries with 2 in parallel for 12 and the other set in parallel the combine both sets in...

On his website Will says there are rebranded MPP Solar models . Does anyone know some of these brands so I can avoid huge shipping charges and not wait a month or more for delivery? ASHATA, ECO-WORTHY, SOME ARE JUST ADVERTISED AS REBRANDED OR GENERIC. Most of them look the same but I don't know...
