Is adding more panels an option for me? I seem to recall during my system design that I could theoretically have 7x100w 12v panels

The dorm fridge was 200 a similar sized 12v fridge is wayyyy more. Plus I would have to re-wire

Panels are all HQST 12v 100w. Inverter is Giandel 2200w...

I have an off-grid trailer setup. Currently 2s3p. Charging 4 x 100ah 12v LifeP04. Using a Victron 150/60 MPPT. I use an inverter to power a dorm size fridge and a TV. All other power consumption is 12v and just led lights and a phone charger. Problem is my campsite is shaded much of the day...

Ok just went out and checked on them. They are back! 11.04v

The batteries are inside the camper. We have been getting lows in the teens and daytime temps in the 30's but also a lot of wind. A bottle of water was frozen inside the camper. Yesterday the DC lights would come on, but today nothing. I think the chins has a built in bms that shuts them down at...

I have 2 chins 12v 100ah lifepo4's. It's been brutally cold here lately. I'm using a victron smartsolar mppt and I have the battery temp sensor. The mppt was set to cut off charge at 5c (probably not low enough?) Came out to the camper and I was showing around 11v, apparently it had been so...

There is a material called Refractory Wool used to line furnaces that are built to heat up metal to red hot tempuratures for forging. Typically used by DIY bladesmiths for home forging knife blades. Its not extremely expensive, is fairly lightweight and flexible. It could be used as some type of...

STOP! DO NOT PURCHASE ANYTHING. I swear man you are about to POTENTIALLY make a multi-thousand dollar mistake. I am new to all this but I am seeing major red flags in your post. Do more research, watch some more videos, search for topics on here. I am new myself and realize already some things...

Thank you. I have worked with AC before but mostly just replacing breakers, switches and outlets. I am adding a remote outlet so I can run an AC fridge and TV without having extension cords running all over the place.

I have the Giandel 2200w inverter that Will recommends for a 400w system. It has the ability to hook up 110v 2-phase (although now Im not sure if its actual 2-phase or not) wire so that I can have a 110 socket away from the inverter. However the only markings on the terminals are an L N and a...

Should I line the area with aluminum sheet panels for further protect myself? Obviously I will install a smoke/CO detector. The compartment is somewhat vented with a filtered vent. I just dont want to wake up in a bed of fire because "china is asshoe".

I'm installing Chins Chinese LiFePO4 12v batteries in a solar camper project. The plan is to install them under the bed in a vented compartment, using typical Prowse blueprints (fuse/breaker locations, wire sizes, etc). I recently watched a few videos of batteries catching fire. What concerns...

I am planning on running a 110v fridge off of a 12v solar system. Other than the fridge I basically only have a very few occasional use 110v items. My question is, would it be more efficient to have a small dedicated inverter solely for the fridge? Its a 60 watt fridge. So maybe a small 100w...
