Can I use my SDS whilst charging?
The Solar SDS Generator is designed to be used as a standalone unit, working just on its own battery bank, that is being recharged either by Solar or Wind or AC mains, in all cases the SDS unit can be used whilst it is connected to any charging means. As an UPS power supply when it is connected to the mains using a AC mains charger. If the main AC supply is dirty or unreliable, then when the mains power fails the battery bank will pick up the load without any disruption to the load. Once mains supply is restored then the batteries will be recharged and the supply will be supported by the AC mains supply.
Can I charge my SDS unit inside?
The solar panel is not very efficient when not placed in direct sunlight.. If a solar panel is located where it receives diffused (mains lighting) sunlight, the solar panel will not have enough power to charge the batteries 100%. For the best results if you need to locate the solar panel indoors always try to locate the panel near a window or conservatory structure. If used in a conservatory or where light can pass directly through a clean window you will see sufficient UV rays to charge the batteries but not guaranteed 100%
Can I use the SDS as a (UPS) back-up supply?
The Solar SDS generator can be used has an UPS power supply. Just connect the mains charger through either the Cigar Socket or directly to the Positive and Negative Terminal located on the back of the SDS unit and power will be supplied to the Inverter unit from the batteries, but will be supported and charged by the AC supply. If the main AC supply is dirty or unreliable, if the mains power drops out, then the battery bank connected to the Solar SDS Generator will pick up the load without any disruption to the load, then when the mains supply is restored, the batteries will be recharged and the supply will be supported by the AC mains supply.
Can I use the lighter cigar socket in my car to charge the SDS?
Yes, most modern cars have alternators that have an output voltage suitable for charging DC to DC. The connection will be via a 12 volt DC to 12 volt Dc cable, available though any Solar SDS Distributor. The connection is through the 12 volt Star (Cigar) socket, located on the back of the generator.
Can I run the unit on one battery?
The simple answer is Yes. The batteries inside the Solar SDS Generator are connected in parallel, if you use only 1 battery you have a capacity of 14 Ah, with two batteries the capacity will be 28 Ah, with either 1 or 2 batteries the voltage will remain at 12 volts. What will be affected is the run time of any appliance. Reducing the battery capacity to only 1 battery will reduce the weight by 4.6 Kg.
Can I recharge the SDS by AC mains?
Yes you can, the SDS is supplied with 12v 4 Amp 3-stage Desk Top charger. This will charge both the Internal and the smaller range external batteries, if you are looking to use the larger External battery options, 50Ah plus up to 150 Ah batteries, it is advisable to use a larger battery charger, may be 12 volt 6, 8 or even 10 amp options. The SDS has been manufactured to charge by solar, wind as well as mains electricity.
Do any of the batteries in the SDS have a “memory effect” ?
You hear people talk about the “memory effect” and that their battery no long affective. Firstly the memory phenomenon or to give it proper name is the Dendrite Affect, is a crystallatine formation of active material on the positive plate, the crystals increase in size concealing large active portions of the plate from the electrolyte. But this only occurs in Nickel based batteries like Ni-Cd and Ni-Mh, not in lead acid batteries.
What most users are experiencing is a problem due to the either battery being left on charge too long (weeks at a time) and increasing the batteries internal impedance or that the battery is only charged for a short period of time, so only a percentage of capacity is put back into the battery (1, 2 or 3 hours), so only 80% capacity is replaced. You also hear people talk about Sulphation and that you must totally discharge the battery to Clean it up at least once every 6 weeks. Wrong, wrong, wrong, Sulphation occurs if a battery is stored for a prolonged periods of time (more than 72 hours for an AGM and 30 days for a Gel battery) in a: –
- Completely discharged state or very low state of charge,
- If it is never fully charged,
- If electrolyte has become abnormally low due to excessive water loss from overcharging and/or evaporation.
Sulphation is the formation of large lead sulphate crystals which cannot be readily reconverted back to lead, lead dioxide and sulphuric acid during the re-charging operation.
Sometimes Sulphation can be corrected by charging very slowly (at low current) at a higher than normal voltage, BUT completely discharging the battery may cause irreparable damage and should not be done.
Do I have to keep my SDS in a cool place as I’m using this in a hot environment?
For max efficiency it is always best to keep both the Solar SDS Generator and it supporting battery bank, both internal and external batteries at a temperature between 15 to 25oC. Keep the unit and batteries out of direct sunlight.
How do I recycle the SDS batteries?
The batteries used internally and externally with the Solar SDS Generator are VRLA, lead acid batteries. Lead is a recyclable commodity and as such, is highly sort after, 95% of a Lead Acid battery can and is recycled; the lead, the plastic casing, copper and brass that is used in the structure of the battery and even the acid. All VRLA batteries should be recycles through the local Authorised Recycling centre.
How do you run 5 LED lights at the same time?
The Solar SDS Generator can be supplied with a adapter that is designed to plug into the Star (cigar) socket and have up to 5 LED lighting strips connected to it, either 15, 30 or 60 LED lighting strips.
How can I run my appliances longer and what appliances can I run?
There are 3 Solar SDS Generator in the range; the 300 watt, 500 watt and 1000 watt units. Each generator runs at 12 volt. Housed within the SDS case are either 1 or 2, 12 volt 14 Ah VRLA batteries, giving a battery bank capacity of 14 or 28 Ah. To this Internal battery bank, external batteries can be added, attached via the 12 volt connections located on the back of the generator. This will increase the SDS’s battery capacity from 14 or 28 Ah to whatever battery capacity has been added, e.g 28 Ah internal capacity + 33 Ah external = 61 Ah. Adding External batteries will increase the run time of any appliance connected to the Solar SDS Generator. Regards to what type of appliance you can run, do not exceed the maximum output of your Inverter.
I don’t have an iPhone so how can play my music on my smart phone?
For iPhone users they place phone/iPod into docking location and turn the volume switch at the back of the SDS to turn on the sound through the SDS speakers. For non IPhone users just connect to the audio in
I’ve read in the manual you have fuses. What are these for and what do these do?
We have two kind of fuses included in SDS unit. The 30A fuses is for the power inverter, totally 4pcs and the 20A resettable fuse is protect the battery and 12V DC rail which includes the cigar socket, USB, etc.
I’m going on a fishing trip so can I take it on a plane?
VRLA BATTERY TYPES (Valve Regulated Lead Acid): SEALED LEAD ACID AGM BATTERY,
a is WET, NON-SPILLABLE, CORROSIVE, CLASS 8 component,
UN REF 2800, PACKING GROUP m, EXEMPT UNDER A67
This means VRLA batteries are sealed, lead acid and will not spill any liquid if ruptured. They are therefore qualified for A67 special provision and can be classed as ‘non-hazardous.’
What does the battery charger LED indicate?
They show the State of Charge of the battery, Red LED shows that the battery as less than 90% capacity is it and will take more than 1 hour to recharge. Amber LED, the battery is between 85 and 100 % recharged, recharge time should be approximately 1 hour and Green LED is showing that the battery is fully recharged and can be disconnected from the Charger.
Always 100% fully charge a battery DO NOT OVERCHARGE it by leaving a trickle charger connected for too long a period. If you are going to be using the battery within the next few days or up to 1 week, then you can leave the battery on charger, but there is no real advantage to this, the battery will be recharged if the correct charger is used within 14 to 16 hours. Self discharge, on a good quality battery is less than 3 % per week. If, however you do leave the battery connected for long periods of time without using it, you will cause more harm than good.
What is the difference between pure and modified sine wave Inverter?
Firstly we must say that both have they uses, but the most fundamental different between these two inverters is Price verses Performance, with the difference between the pure sine wave and modified sine wave inverters lies in the type of sign wave they will deliver and the Power Load they can handle.
A modified sign wave is basically a square wave that has been derived by a processor and looks like a Saw Tooth waveform, resting at zero volts for a short time before switching up for a positive voltage and down negative, simulating a Square Sine Wave. Whereas the pure sine wave inverter’s output are an evenly spaced hills and valleys at a steady frequency.
Whilst an AC motor will run off a modified sine wave, its operational efficiency is nearly twenty percent less than it would be if used on a pure sine wave inverter, because it is being feed a digital voltage and not a smooth positive and negative sign. Running AC motors from inverter using Modified sine wave may also damage the motor due to heat building up in the unit
A pure sine wave inverter is compatible with all types of electronics and the more sensitive, specialized equipment such as laser printers and audio equipment, AC and DC motor power applications, where as a modified sine wave inverter will not be compatible. Where the modified inverter units do work, is with these electronic devices that do not have a Surge Fact, such as LED lighting, phone chargers and little wattage equipment.
Where is the AC Charger input?
AC charging points, AC charging can be achieved using the “star Connector (cigar Type connector) or via the Positive/Negative terminals both allocated on the back of the Solar SDS unit. The SDS unit as a common 12 volt rail between the internal batteries and the Input/output connector, so either can be used.
Where can I buy new batteries for the SDS?
The SDS unit uses deep cyclic 12v 14Ah Low Maintenance batteries, which can be obtained anywhere around the world. However the SDS batteries are high Cyclic, Deep Discharge batteries and are specified for the SDS units. Our key distributors around the world will be able to offer our full range of accessories and replacement components; do not use “Float” or cheap substitute battery types, you may damage the generator and the performance will be affected.
