I WOUL LIKE TO kNOW IF IT WORK FINE WITH SOLAR what type of charge controller should I get to work with one 250 watts panel and 2 deep cycle Batteries

Unfortunately I haven't installed my solar panel yet. So I cannot answer this question.

The instructions doesn't give enough explanation. I called the company for my inverter and asked if solar is compatible with their inverter hooked up to the charge controller. They said to keep the inverter connected to the battery. The only thing I can think of is using a 12 volt light or a small apliance could be connected directly to it instead of using the battery power. If a 12 volt light is connected directly you are taking advantage of the solar imediatly. If the same light was connected to the battery instead, the charge controller doesn't let the solar charge the battery until it drops to a certain voltage. So solar panel isn't being used to its full advantage.

you will need a 10 amp charge controller for one of these or a 20 amp charge controller for two.The charge controller will have adjustable settings "you set"I suggest a renogy 30 amp pwm controller for three reasons it will give you room to add more panels its cheap under $35 and its all you would need to accomplish battery charging in 12 or 24 volt mode,I hope this helps

Without a charge controller battery life will be compromised, due to heat issues accidents may happen as well. MPPT type charge controller is most appropriate for any battery voltages ie; 12, 24 ..... Since this panel is 24v a PWM charge controller will work fine for 24v battery banks. Charge controller is highly recommended.

Depends on what you are going to use it for. If you are going to use your Setup for Emergency Lights, Battery Chargers, Small Appliances the Inverter you use will draw harder off of the battery the more devices you use. I use one 50 watt Solar Panel, Charge Controller, Inverter and two of these Deepcycle 35aH batteries for power outages, emergencies etc. A Small Solar Panel will just trickle charge the battery and you won't be able to use it for powering much before it drops down to the minimal low voltage. A 50 watt Solar Panel is probably a good starting point, then go from there as to what you need to meet your needs. Depends on what you are going to use it for.

I would advise against running it in a two batteries to one panel setup. If one battery went bad it could/will cause the loss of the other battery. The charging controller in this unit is meant to work in a one to one relationship to a single battery. Properly wired it could possibly work as a temporary solution. Is it advised? No. Eventually there will be a massive failure when one battery in the circuit has problems and an overcharge hits the remaining good battery. I would suggest a Battery Tender 022-0165-DL-WH. This is a dual battery charger but is not solar powered.

First, I bought one to keep a deep cycle battery charged up. Second, I would not use the 160 watt panels as they would not be cost effective (you would probably need lots).Instead look at the 250-300watt panels. As to the #, it depends on how much power you consume, and how much of that you want to generate, ie, 5-10KWH per day.

If you are using it to keep batteries charged, you do not need a "charge controller" for 5 Watt panels. For more than 5 watts it is best to use a charge controller. You do not neet a circuit breaker or a built in volt meter. When it is connected to a battery, you cannot tell if it is working with a voltmete. You can check it out when it is not connected to a battery with a voltmeter. It may read as high as 24 volts DC (open circuit). If your plan is to charge a battery that has been used on a boat, it may not be a large enough (not enough watts) to charge a battery in any reasonable time period. 5 watt panels are good for keeping batteries fully charge while being in storage or not in use for long period of time. Maximum current available is about 350 milliamps. It would take well over 129 hours to add back 45 amperes to a 90 amp-hour battery. If you use a larger solar panel, then you will want to use a "charge controller" made for a solar panel. Hope the above helps. Ralph

For 500 watts I think the 30 Amp or larger (30 amp is rated at 450 watts max) charge controller might be a better match. Also this is a charge controller it doesn't really power anything but is meant more for charging of a battery system. You could then use the battery system either with or without an inverter to power your devices.

I have been using the Brunton Solar Controller 12-Volt Battery Charge Monitor with my panel for the past year and it seems to work just fine, the panel keeps my battery on a sailboat charged without over charging the battery.

I have 820 watts of solar and I have the Morningstar MPPT 45 with 6 batteries and works fine. The mppt 45 will only allow me 45 amps, but if I produce more it will not hurt that controller.

Hello JDT,The Renogy 40 Amp MPPT Charge controller can support up to 3 of the Renogy 250 Watts 24V Monocrystalline panels at 24V

This model will handle a maximum of 100 volts of DC output from your solar panels, so your 48 volts is well withing its limits. If your system uses 12 volt batteries, which is most common, and your panels produce no more than 130 watts of maximum power (260 watts if your electrical system is 24 volts) this controller will do the job well. This is a great little controller and I'm totally satisfied with it, and the price is very fair.

You've probably checked on line, but this is a good site to reference http://www.chargingchargers.com/tutorials/solar.html 25 milliamps is really small, and may not generate enough watts to bring the controller into play. I connected the controller to a largish solar panel, output approx 20 volts, for keeping my boat battery topped up.. the combination seems to work well at this level. Hope this helps.

No you will need a charge controller such as this one Docooler Solar Charge Controller Solar Panel Battery Regulator Safe Protection (10A) There is a overcharge protection circuit within the charge controller. How long it will take depends on how low it is and how much sun is available.

If you have 500 watts of solar collecting capacity my understanding is that it would exceed the capacity of this controller. I recommend getting a 40amp MPPT controller. I got this controller for testing purposes but even my two panels rated at max 140watts each would exceed the capacity of this charge controller in full sun.

Look at the max amperage of the solar panel and multiply it by 4 if this exceeds 30 amps you will need a larger charge controller. Without knowing the max amperage of the solar panels my best guess is that it will be close. I suggest getting a larger controller.
