You have 2 inputs amp limits in your post 10amp and 20 amp. Sunnyboy model? One string does add voltage. Use the Voc and add 10 percent to be safe so as not to fry the inverter. One string will have output diminished if one panel gets shaded. Two strings would have only that string degraded...

I bought 8 -100 watt 9BB BougeRV panels on amazon for about that. They are showing a deal on each panel right now. There is 9 dollar coupon to apply on one panel. Just buy one per order , I did and it worked. Great panels. Connected 4s2p on a victron 150/60 SCC

Well the inverters woul have to have a much higher voltage limit.. It doesn't look like there are any that will do this. The voltages are to low for most string inverters and too high for individual inverters like an enphase. I guess at this point I just won't attempt it. Thanks for the...

The solar to battery controller is a Victron 150/60. I knew it was OK.. But I want to grid tie these when not using the trailer. Most of the inverters are 90v max. Thank you for the information. I know the 90v is getting close. But I figured the mppt will lower the voltage after...

I bought bougerv 100 watt 9BB panels. 800 watts, 4s2p I am trying to figure the max voc but cannot find the info to use. It only show +-3% but does not tell if that is max in cold weather. These are on my trailer but want to put a grid tie when it is parked. Thanks for your help.

Anyone have any panels from Spartan Power. Sold by inverters r us. They are 200 watt panels. Looks like a good deal... until its not. What do you think.

I have 2 solar systems that are grid tied. They use string inverters. When the power goes out, how do the inverters detect that the main power is off and do not see each other producing power and just stay on? I have had these for years and just now thought of this. This is just for my...

The converter is on it own breaker in the fuse panel. I thank you for the information. The inverter will be here in a few days. I will go over the manual in detail then.

I am wanting to install this in a travel trailer to the main breaker panel. I am planning on using an automatic switch (go power ts-30). It has a 30 amp service. I understand that the UL458 standard calls for the neutral and ground to bond when off grid, But does this mean the neutral is a...

It would do what you want except it doesn't provide AC and the 30 amp out is not the 55 amp capacity of the original converter. I would not use it as a replacement. Your appliances pull from the battery and you are charging at the same time so any draw over 30 amps would draw your battery...

Travel Trailer upgrade LiFePo4 - I installed an AmpereTime 200 Ah LiFePo4 with the 200amp bms. No inverter just figured the 200 bms would last longer and future proofing. The trailer still has the original Converter 55 amp SLA type charger {WFCO 9855} built in to the fuse box. I have 200...

I know your post is old but, the Renogy panel is a short voltage of 25 volts If you put it in series it has the same voltage. All panels work like this. When in series the voltages add up. So actual voltage say 20 v + the jaboni 18.8 is about 38.8 volts in full sun. The amps will...

You could leave the panels alone and use one of these https://www.amazon.com/AITRIP-Converter-Constant-Electric-Equipment/dp/B08TWKK5Z9/ref=sr_1_21?dchild=1&keywords=boost+converter&qid=1631113681&s=electronics&sr=1-21

You should disconnect the converter from the Lead Acid battery when using the LIFEPO4 as your shore power. Unless the Lifepo4 is charged up and the lead battery needs charging. Leaving the converter connected just loses power during conversion. My opinion. Also the Overkill BMS 24v unit I...

Thank you. I wanted to know if it was safe. You helped me out with that.
